Bridget Riley
Bridget Louise Riley (born 24 April 1931) is an English painter whose works exemplify the Op Art movement through the use of geometric patterns that generate perceptual illusions of movement, vibration, and color shifts.[1][2]
Born in London to a family with ties to printing, Riley trained at Goldsmiths' College, graduating in 1952, and later at the Royal College of Art's Painting School in 1955, where she initially engaged with pointillist techniques inspired by artists like Georges Seurat before shifting to abstract optical effects.[3][4] Her career gained prominence in the 1960s with black-and-white compositions employing wavy lines, zigzags, and contrasting tones to provoke dynamic visual responses, establishing her as a leading figure in Op Art alongside contemporaries like Victor Vasarely.[5][6]
Riley's innovations extended to color in the late 1960s, incorporating stripes and curves to evoke spatial depth and rhythm, as seen in works like Movement in Squares (1961).[2] She achieved significant recognition, including being the first woman to win the painting prize at the Venice Biennale in 1968, and has since maintained a prolific output, with her abstract explorations influencing perceptions of vision and form.[7] Her pieces are held in major collections, underscoring her enduring impact on modern art without notable controversies, focused instead on empirical exploration of optical phenomena.[1]
Early Life and Education
Childhood and Family Background
Bridget Riley was born on 24 April 1931 in Norwood, London, to John Fisher Riley, a printer from Yorkshire who owned his own printing business, and his wife.[7][4] The family, which included Riley and her sister, belonged to the middle class and relocated from London to Lincolnshire in 1938 following her father's business expansion.[7][8] At the onset of World War II, the family evacuated to Padstow in Cornwall for safety, where Riley spent formative childhood years amid coastal environments, fostering an early perceptual awareness of natural light, wave movements, and atmospheric changes through direct observation.[9][10]Formal Academic Training
Riley began her formal art education at Goldsmiths College, University of London, enrolling in 1949 and studying there until 1952. Under the guidance of instructor Samuel Rabin, who taught from the 1940s to the 1960s and emphasized figurative drawing and sculpture, she received training in observational skills, life drawing, and rendering the human form from live models.[11][12] This curriculum provided her with foundational technical proficiency in draftsmanship, though it adhered to traditional academic methods focused on representational accuracy rather than innovation. In 1952, Riley transferred to the Royal College of Art's painting school, completing her diploma in 1955. The program's emphasis on classical techniques, including still life, portraiture, and landscape studies in a semi-impressionist vein, exposed her to historical masters such as the Impressionists and Vincent van Gogh, but the faculty's conservative outlook offered minimal direction for experimental work.[7][13] She produced competent figurative drawings and nature studies during this period, honing precision in line and form, yet grew frustrated with the institution's rigid norms and lack of support for abstract exploration.[4][14] Following graduation, Riley encountered significant personal and professional obstacles that interrupted her early career trajectory. In 1955, she returned to her family home to care for her ailing father, which contributed to a mental breakdown necessitating six months of hospitalization in 1956.[15] This episode, compounded by financial instability and artistic doubt, led to a prolonged hiatus from sustained painting around 1959, during which her output diminished sharply as she prioritized recovery and temporary teaching roles.[16] These challenges underscored the practical limits of her academic training in preparing for independent professional demands.Key Influences and Artistic Development
Impact of Seurat's Pointillism
In 1959, Bridget Riley encountered Georges Seurat's Bathers at Asnières (1884) during a visit to the National Gallery in London, an experience that profoundly impacted her artistic direction by highlighting the optical mixing of colors through divisionist techniques.[17][18] This led her to produce a direct copy of the painting that year, marking her initial engagement with pointillism's capacity to generate luminosity and perceptual depth via juxtaposed dots rather than blended pigments.[19] Riley adapted Seurat's pointillist method not for static color harmony but to induce dynamic perceptual vibrations and illusions of movement in the viewer's eye, diverging from Seurat's more fixed optical blending by emphasizing rhythmic patterns that exploit retinal afterimages.[20] Early sketches from this period demonstrate her experimentation with fragmented forms to create flickering effects, prioritizing the active role of human vision over representational fidelity.[21] The 2015–2016 exhibition Bridget Riley: Learning from Seurat at the Courtauld Gallery in London curated works including her 1959 copy, Seurat's studies, and Riley's subsequent drawings to trace this methodological lineage, underscoring how pointillism prompted her pivot from figurative painting to abstract optical phenomena without implying direct stylistic imitation.[18][21]Broader Influences from Modernism and Perception Studies
Riley's engagement with Futurist art, particularly the works of Umberto Boccioni and Giacomo Balla, informed her interest in visual dynamism and the representation of motion, encountered during a 1960 trip to Italy where she studied their paintings and sculptures emphasizing speed and energy.[7][4] This exposure encouraged her to explore how static forms could evoke temporal effects through pattern and contrast, aligning with Futurism's empirical dissection of perceptual change.[22] From broader Modernist currents, she absorbed the geometric rigor of Piet Mondrian's compositions, which prioritized balanced color fields and lines to achieve harmonic visual order, as well as the Bauhaus emphasis on elemental shapes and their perceptual interactions under functional design principles.[23][24] These influences shifted her toward a structured analysis of form, rejecting decorative excess in favor of patterns that directly engage the eye's innate responses to rhythm and proportion. Impressionist and Post-Impressionist approaches to light—such as Pierre-Auguste Renoir's handling of atmospheric luminosity—further shaped her examination of how color gradients produce illusions of depth and flux, extending beyond mere representation to the mechanics of observation.[25] In perception studies, Riley integrated Gestalt principles, which describe the brain's tendency to organize disparate elements into coherent wholes through proximity, similarity, and closure, applying these to generate emergent visual structures dependent on viewer physiology rather than artist-imposed narrative.[26] She drew on physiological optics, informed by mid-20th-century research into retinal processing and afterimages, to exploit how contrasting stimuli induce involuntary eye movements and color interactions, prioritizing causal mechanisms of vision over interpretive subjectivity.[27] Riley eschewed self-identification as an "abstract" artist, viewing such terms as misleading for work rooted in perceptual realism, where paintings function as "visual events" or "actions" that deliver unmediated encounters with the eye's operations, distinct from emotional abstraction or symbolic intent.[28] This stance reflects a commitment to empirical viewer experience, grounded in the objective realities of optical response rather than subjective expression.[7]Major Periods in Her Oeuvre
Early Black-and-White Works (1960s)
In the early 1960s, Bridget Riley shifted to abstract compositions using black, white, and occasionally gray, employing geometric patterns to evoke illusions of motion and spatial distortion on static canvases. These monochrome works relied on high-contrast repetitions of simple shapes—such as squares, stripes, and curves—to trigger perceptual responses including vibration and expansion, effects grounded in the physiology of human vision where overlapping patterns interfere to produce dynamic interference.[29][7][30] A pivotal early piece, Movement in Squares (1961), features a grid of alternating black-and-white squares intersected by wavy black lines, generating moiré patterns that simulate undulating movement across the surface. Painted in tempera on hardboard and measuring 123.2 by 121.2 cm, the work demonstrates Riley's method of leveraging elementary forms to induce verifiable optical phenomena, such as oscillating afterimages observed in viewer studies of pattern-induced retinal fatigue. This painting, exhibited in her first solo show at Gallery One in 1962, established her focus on empirical visual mechanics over representational content.[31][32][33] Riley's inclusion in the Museum of Modern Art's The Responsive Eye exhibition (February–April 1965) amplified Op Art's prominence, showcasing pieces like Current (1964), a black-and-white composition of curved horizontal stripes that distort into wave-like flows, featured on the catalogue cover. The exhibition emphasized perceptual illusions—moiré interference, luminosity shifts, and induced motion—drawing from scientific investigations into eye physiology, with Riley's contributions highlighting how precise edge contrasts compel involuntary eye movements and aftereffects.[34][35][36]Transition to Color and Evolving Geometries (1970s–1990s)
In the 1970s, Riley expanded her Op Art practice by intensifying the use of color to amplify perceptual dynamics, moving beyond the monochromatic contrasts of her earlier decade to explore interactions between hues that induce vibration and spatial ambiguity. Works such as Paean (1973) exemplify this shift, employing bold juxtapositions of red, blue, and green to create rhythmic undulations, where color gradients mimic the optical effects of light filtering through foliage or water surfaces observed in nature.[37] This evolution stemmed from empirical studies of color theory, with Riley mixing pigments precisely to exploit complementary pairs—such as orange against blue—for heightened chromatic tension, as verified through viewer responses in controlled exhibitions.[38] By the 1980s, Riley's geometries grew more fluid, incorporating mathematically derived curve progressions that simulated natural waveforms, such as those in ocean swells or leaf patterns, while maintaining rigorous geometric underpinnings to ensure reproducible illusions. Her stripe variations, including vertical bands in series like the Egyptian-inspired palettes, used a limited set of four to five hues—ochres, blues, and greens drawn from ancient tomb paintings—to generate moiré patterns and illusory depth, as seen in KA 2 (1980).[39] [40] These compositions adhered to principles of modular repetition, where stripe widths followed arithmetic sequences to control expansion and contraction effects, informed by direct observations during her 1980 trip to Egypt's pyramids and temples.[41][7] Throughout the 1990s, Riley refined these elements into hybrid forms blending stripes with elliptical curves, prioritizing causal relationships between form and perception over decorative intent; for instance, her adaptations of undulating motifs preserved the primacy of viewer-induced movement, with color choices calibrated to empirical tests of retinal response rather than arbitrary aesthetics. This period's output, including screenprints and canvases with interlocking color blocks, demonstrated sustained innovation in perceptual realism, where geometric precision—often plotted via preliminary drawings with logarithmic scaling—countered entropy in visual fields to evoke sustained dynamism.[42][43]Large-Scale Murals and Installations
Bridget Riley has produced several site-specific murals and installations that adapt her geometric patterns to architectural scales, ensuring optical illusions remain effective across viewer distances typical of public spaces. These works demand precise scaling of motifs—such as waves, stripes, or discs—to counteract the diminished perceptual impact of enlarged forms, with patterns calibrated for distances of approximately 3 meters or more to evoke movement and shimmer.[21] In 2019, Riley completed Messengers for the National Gallery in London, a 10 by 20 meter wall painting encircling the Annenberg Court with floating colored discs that mimic drifting clouds, drawing from Seurat's pointillism and Constable's skies. The installation transforms the space into an immersive optical environment, where discs appear to shift against a white ground, tested for consistency in a high-traffic gallery setting.[44][45] Riley's 2014 murals at St Mary's Hospital in London, spanning three floors of the Queen Elizabeth Queen Mother Wing, mark her first major public commission in 27 years and integrate seamlessly with the building's architecture through collaboration with its designers. These striped patterns maintain continuity across walls and corridors, engineered to deliver sustained visual dynamism for patients and visitors at varying proximities.[46][47] For the British School at Rome, Riley executed Verve in 2023, a ceiling mural covering four barrel vaults in the foyer using an "Egyptian palette" of vibrant hues; development spanned a year, including a full-scale model to resolve curvature and projection challenges inherent to vaulted surfaces. This ensured unbroken pattern flow and preserved illusory depth despite overhead viewing angles.[48][49] At the Chinati Foundation in Marfa, Texas, Riley's untitled wall painting, unveiled in October 2023, encompasses six of eight walls in a dedicated building—her largest work to date—featuring elongated color bands that exploit the room's dimensions for enveloping perceptual effects, with motifs proportioned to the site's vast scale and natural light variations.[50] Riley's large-scale projects demonstrate technical proficiency in substrate adhesion and pigment stability for enduring public exposure, with no documented failures in optical integrity over time in these installations.[51]Theoretical and Intellectual Output
Writings on Visual Perception
In her 1965 essay "Perception is the Medium," published in ARTnews, Bridget Riley articulated a foundational defense of Op Art against characterizations of it as illusory trickery or superficial novelty, positing instead that visual perception itself constitutes the essential medium of artistic experience.[27] She argued that paintings engage the viewer's innate physiological responses to optical stimuli, such as contrast, rhythm, and movement, thereby eliciting direct, bodily states of awareness rather than intellectual interpretation or cultural overlay.[27] Riley emphasized empirical observation of the eye's mechanisms—drawing on phenomena like afterimages and induced motion—to assert that such responses are universal and biologically rooted, predating subjective or relativist interpretations.[28] This physiological grounding underpinned Riley's rejection of cultural relativism in visual experience, as she contended that art's potency derives from activating the retina and optic pathways independently of learned associations, fostering a raw encounter with form and light.[27] In the essay, she critiqued prevailing dismissals of Op Art by highlighting its alignment with verifiable perceptual science, where geometric patterns provoke measurable neural firings akin to those in natural vision, thus elevating the genre beyond mere retinal games to a probing of human sight's capacities.[52] Riley's subsequent writings, compiled in The Eye's Mind: Collected Writings 1965–2009 (revised and expanded to 2019), extended these ideas by interrogating abstraction's potential pitfalls when divorced from perceptual immediacy.[53] In reflections such as "Perceptual Abstraction: A Reflection," she warned against abstract forms that prioritize conceptual detachment over the viewer's lived optical engagement, advocating instead for constructions that harness color contrasts and linear tensions to mirror the dynamic flux of seeing.[28] These texts underscore her view that effective abstraction must remain tethered to empirical visual processes, critiquing modernist tendencies toward static or hermetic geometries that neglect the eye's active role in constructing reality.[28]Curatorial Roles and Statements on Artistry
In 2002, Bridget Riley co-curated the exhibition Paul Klee: The Nature of Creation at the Hayward Gallery in London with Robert Kudielka, selecting works from 1914 to 1940 that demonstrated Klee's systematic exploration of generative processes in nature and form.[54] In her accompanying essay "Making Visible," Riley emphasized Klee's analytical method of rendering invisible structural dynamics perceptible, underscoring the curator's role in highlighting art's capacity to reveal perceptual mechanisms rather than subjective narratives.[55] This curation reflected her advocacy for exhibitions that prioritize empirical observation of visual phenomena over decorative or ideological framing.[56] Riley's statements on artistry consistently stress the artist's function as a facilitator of unmediated perceptual encounters, rejecting infusions of personal ego or external agendas. She has asserted, "I have always believed that perception is the medium through which states of being are directly experienced," positioning the artist as an enabler of optical immediacy rather than an interpreter of symbolic content.[27] Countering romanticized notions of artistry as unchecked expression, Riley describes the process as disciplined inquiry: "For me, drawing is an inquiry, a way of finding out – the first thing that I discover is that I do not know," where the practitioner records and clarifies observed visual dynamics without preconception.[57] She has explicitly opposed commercial exploitation that dilutes perceptual purity, prohibiting reproductions of her works for advertising to safeguard their role in evoking unaltered sensory responses.[58] Similarly, Riley prioritizes universal truths of form and color over political messaging, viewing such impositions as distortions of art's core directive to contribute rigorously to contemporary visual language through empirical testing of geometric and chromatic relations.[57] This stance aligns with her broader curatorial philosophy, evident in selections that foreground perceptual honesty as the artist's ethical obligation.[59]Exhibitions and Institutional Recognition
Pivotal Solo and Group Shows
Bridget Riley's inclusion in the group exhibition The Responsive Eye at the Museum of Modern Art in New York, held from February 25 to April 25, 1965, marked a defining moment for Op Art, featuring her black-and-white painting Current (1964) alongside works by artists such as Victor Vasarely and Richard Anuszkiewicz, and drawing over 47,000 visitors in its initial weeks despite critical controversy over its perceptual effects.[34][60] In 1968, Riley represented Great Britain with a solo presentation in the British Pavilion at the 34th Venice Biennale, showcasing transitional color works including Rise 1 (1968) and Late Morning (1967–1968), which highlighted her shift from monochrome to chromatic illusions and garnered international attention for her command of visual rhythm.[61][35] Major retrospectives followed, such as the comprehensive survey at Tate Britain from October 9, 2003, to January 18, 2004, spanning her career from 1961 onward with over 40 paintings grouped chronologically to demonstrate evolving phases in her geometric and perceptual experiments.[62][63] A spotlight display at Tate Britain, running from July 21, 2025, to June 7, 2026, presents select works including the newly donated Concerto I (2024), a large-scale painting engaging with Impressionist influences through curving forms and vivid hues, underscoring her ongoing exploration of movement in color.[64][65]Awards, Honors, and Official Accolades
In 1968, Riley became the first woman to receive the International Prize for Painting at the Venice Biennale, recognizing her contributions to optical art.[61] She was appointed Commander of the Order of the British Empire (CBE) in 1974 for services to art.[66] In 1999, she was named Companion of Honour (CH), one of only 65 living members of this order at the time, honoring sustained artistic achievement.[66] Riley received the Praemium Imperiale for painting in 2003, an award from the Japan Art Association for lifetime accomplishment in the arts.[2] In 2009, she was awarded the Kaiserring of Goslar, Germany, for her influence on perceptual painting.[2] The Sikkens Prize followed in 2012, the first awarded to a woman, specifically for her precise and innovative application of color in abstract compositions.[67] That same year, she received the Rubens Prize from the City of Siegen.[68] She holds honorary Doctor of Letters degrees from the University of Oxford (1994) and the University of Cambridge (1995), reflecting academic acknowledgment of her perceptual theories and technical rigor.[69] Her works are held in major public collections, including the Tate galleries in the UK and the Museum of Modern Art in New York, signifying enduring institutional validation of her oeuvre's impact on visual dynamics.[1][70]Influence, Legacy, and Controversies
Effects on Subsequent Artists and Optical Art
Bridget Riley's pioneering Op Art works, characterized by geometric patterns inducing visual instability, directly influenced subsequent perceptual artists including Richard Anuszkiewicz, whose color-based illusions echoed Riley's emphasis on retinal response, and Richard Allen, who extended black-and-white undulations into modular abstractions in the late 1960s.[7] Her techniques also resonated with later painters like Ross Bleckner, whose 1980s stripe paintings explored perceptual distortion in abstract expressionism, and Philip Taaffe, who appropriated Op motifs in layered silk-screen works from the 1990s onward to probe optical interference.[7] These transmissions highlight Riley's role in propagating viewer-dependent effects beyond pure geometry. Riley's insistence on art as a participatory phenomenon—where the viewer's eye generates motion and rhythm—helped legitimize viewer-centric paradigms over traditional artist-centric narratives, empirically shaping graphic design practices that prioritize perceptual engagement, such as rhythmic pattern-making in branding and digital interfaces since the 1970s.[71] Op Art principles have since migrated to kinetic sculptures and digital media, with algorithms simulating Riley-esque moiré patterns in interactive installations and screen-based art, sustaining their applicability in motion graphics.[72] Contrary to early dismissals of Op Art as ephemeral, Riley's contributions endure in visual perception research, where her static patterns, as in Fall (1963), serve as stimuli for studying gaze stability, illusory motion, and neural processing of contrast, with applications documented in neuroscientific experiments as late as 2012.[73] This scientific utility underscores Op Art's lasting causal impact, informing fields from cognitive psychology to interface design without reliance on transient trends.[7]Plagiarism Disputes and Appropriation Debates
In the 1960s, during the surge in popularity of Op Art, Riley's geometric patterns were frequently appropriated for commercial fashion designs, such as dresses and textiles in the Mod era, often without attribution or permission, which she viewed as diluting the perceptual and intellectual intent of her original works.[74] Riley actively pursued copyright enforcement against these unauthorized reproductions, expressing frustration at being "misunderstood and used" amid the mass commercialization that treated her motifs as freely replicable decorations rather than protected perceptual experiments.[74] Unlike contemporaries like Victor Vasarely, who embraced such adaptations to democratize art, Riley opposed the commodification, insisting on safeguarding the specific sequences and visual effects as proprietary intellectual labor.[75] A prominent later instance occurred in 2013, when Riley initiated a plagiarism lawsuit in Berlin against German artist Tobias Rehberger over his wall-sized black-and-white checkerboard installation, Untitled (After Movement in Squares), commissioned for the German National Library, which closely derived from her 1961 painting Movement in Squares.[76][77] The work, concealed initially due to the dispute, prompted Riley to demand its removal, arguing it infringed on her copyright by replicating the dynamic square motifs without transformative justification.[78] By January 2014, the parties reached an out-of-court settlement, with Riley waiving further claims against Rehberger's related Clockobject as a gesture of goodwill, though the core installation's fate underscored her commitment to defending motif originality.[76][78] Riley's positions in these cases emphasized that the proprietary value lay not merely in static images but in the engineered perceptual responses—sequences of lines, contrasts, and rhythms constituting labor-intensive innovation—rejecting notions of ideas as open-source in visual art.[74] No additional major legal challenges have been publicly documented beyond these episodes, reflecting her selective but firm enforcement to preserve artistic integrity over permissive influence.[77]Critical Reception and Debates
Positive Assessments of Technical Innovation
Bridget Riley's paintings have received acclaim for pioneering optical illusions that produce empirically verifiable perceptual effects, as demonstrated through controlled scientific experiments on viewer responses. Researchers have shown that her geometric patterns trigger motion illusions via involuntary eye movements, such as microsaccades during fixation, leading to measurable distortions in perceived movement and time duration.[79][73] For example, exposure to reproductions of her works, like variants of Fall, results in quantifiable gaze instability that generates the illusion of dynamic motion in static images, with afterimage persistence and kinetic sensations replicable across participants.[80][81] Critics and scholars have commended Riley's technical precision in constructing these effects, elevating simple geometric forms through rigorous patterning that achieves causal specificity in visual outcomes, thereby countering the indeterminacy of gestural abstraction prevalent in mid-20th-century art. Her methodical use of alternating contrasts and repetitive motifs ensures illusions arise predictably from physiological mechanisms, as evidenced by studies linking her compositions to specific neural and ocular responses.[23][82] This approach has been highlighted for its innovation in exploiting verifiable principles of visual perception, with Riley herself articulating that "perception is the medium through which states of being are directly experienced."[27] The empirical foundation of Riley's innovations has contributed to advancements in vision science, where her patterns serve as stimuli in experiments probing oculomotor control and illusory phenomena, influencing standards in perceptual design by providing models for predictable sensory engagement. Peer-reviewed analyses confirm that prolonged viewing of her Op Art elicits temporal distortions and stable illusion metrics, underscoring her role in bridging artistic creation with scientific inquiry into human sight.[83][84]Criticisms of Superficiality and Commercialism
Critics in the 1960s, including Barbara Rose, dismissed Op art, including Riley's contributions, as "mindless" and lacking substantive depth, viewing its optical effects as superficial gimmicks rather than profound artistic statements.[85][86] Clement Greenberg similarly labeled such work "novelty art," critiquing its reliance on perceptual tricks over enduring aesthetic or intellectual content.[86] These assessments positioned Riley's black-and-white patterns, such as those evoking movement through contrast, as akin to outdated Bauhaus exercises in visual mechanics, obsolescent in their formulaic repetition and failure to transcend decorative function.[86] Detractors have argued that the viewer fatigue induced by Riley's illusions—manifesting as eye strain, frustration, or the compulsion to avert one's gaze—reveals inherent flaws in the work's design, interpreting these responses as evidence of superficiality rather than intentional engagement with perception.[87] For instance, prolonged exposure to pieces like Movement in Squares (1961) often leads observers to abandon viewing due to visual instability, which some contend undermines any claim to depth, reducing the art to transient optical novelty without sustained emotional or conceptual resonance.[87] This perspective contrasts engineered "features" of retinal response with critiques framing them as limitations, prioritizing works that reward extended contemplation over those provoking immediate sensory overload. The swift co-opting of Riley's motifs by commercial sectors, particularly 1960s fashion and advertising, fueled arguments that her style eroded the boundaries of fine art, devolving into reproducible decoration akin to "framed wallpaper."[88][13] Images from works like Current (1964) proliferated in Mod-era textiles and ads, prompting accusations that such accessibility commodified the art, stripping it of exclusivity and elevating superficial pattern-making over unique creative endeavor.[88][89] While Riley resisted through legal actions against unauthorized reproductions, this very ubiquity reinforced detractors' views that Op art's appeal lay in its gimmicky versatility for mass markets, diluting its status as elite aesthetic inquiry.[89][13]Art Market, Philanthropy, and Later Career
Market Valuation and Sales Records
Bridget Riley's artworks have commanded high prices at auction, with her secondary market demonstrating robust demand driven by limited availability and renewed interest in Op Art. As of 2025, she ranks 142nd among the world's top 500 best-selling artists by auction turnover.[90] Her paintings and prints have seen consistent appreciation, with print sales turnover increasing from £203,531 in 2015 to £968,759 in 2024, reflecting a quadrupling in value amid scarcity on the market.[91] Key record sales include Gala (1978), which fetched £4.4 million at Christie's London during the 2022 Modern British Art Evening Sale, surpassing its £3.5 million estimate.[92] Another benchmark is Untitled (Diagonal Curve) (2006), sold for £4.34 million ($5.81 million) at Christie's London in June 2016, marking a record at the time that highlighted escalating values for her geometric abstractions.[93] Zing 2 (1980) achieved £3.3 million, further underscoring demand for her color-based works.[94]| Artwork | Sale Date | Auction House | Price |
