About this work

Created in 1968, Bridget Riley’s *Nineteen Greys* series is a masterful exploration of tonal variation, using subtle gradations to evoke depth and a sense of motion. In each of the four screen prints, Riley meticulously arranges 19 distinct shades of grey in a precise, ordered formation, inviting viewers to engage with the nuances of tone as they shift across the surface. Though monochromatic, the prints give an impression of dynamic movement, as the gradation of greys seems to ripple and flow, creating a tension between flatness and spatial illusion. This optical play exemplifies Riley’s ability to achieve powerful effects with simplicity and precision.Riley’s skill in handling tonal shifts allows her to create a mesmerizing visual rhythm that captivates the eye, even without the use of color. The gradual shifts between the shades in each piece lend the prints a three-dimensional quality, as certain greys appear to advance while others recede. This careful manipulation of light and shadow echoes Riley’s broader body of work, where she often employs slight variations in form and hue to explore how perception can be altered by the arrangement of basic visual elements. *Nineteen Greys* is thus a study in how minimalism can yield intricate optical illusions that evoke a strong sense of movement.Through *Nineteen Greys*, Riley reaffirms her position as a leading figure in Op Art, pushing the boundaries of perception with a restrained and carefully balanced palette. Each print in this series encourages viewers to look closely, observing the almost imperceptible transitions between tones that give rise to a sense of spatial depth. These works are quintessentially Riley, embodying her ceaseless dedication to experimenting with visual perception, form, and tonal precision. The series highlights her talent for transforming simple gradations into immersive experiences, where grey becomes more than a color—it becomes a shifting, almost kinetic presence.

About Bridget Riley

Bridget Riley

Life and Practice

Bridget Riley (b. 1931, Norwood, London) is one of the foremost figures in twentieth-century abstract painting, internationally celebrated as a pioneer of Op Art. Educated at Goldsmiths College and the Royal College of Art, Riley spent time teaching before dedicating herself fully to painting in the early 1960s. Her early work — strict geometric compositions in black and white that induce powerful perceptual effects of motion, vibration, and depth — established her as a key innovator in art's engagement with visual perception. Movement in Squares (1961) and Fall (1963) are among the most celebrated works of the period, and remain among the defining images of British postwar art.

Riley was awarded the International Prize for Painting at the 1968 Venice Biennale, cementing her international reputation. From the late 1960s, she began introducing colour into her work, working first with carefully limited Egyptian palettes and later a full range of hues, exploring stripe-based and diagonal compositions in which colour interaction becomes the primary subject. Her series including Orphean Elegy, The Seasons, and Rajasthan demonstrate the sustained rigour and beauty of this investigation. She continues to work from studios in London and Cornwall.

Two Distinct Periods

Riley's career divides into two widely recognised phases. Her black-and-white works of the early 1960s are the most immediately iconic: paintings that create genuine optical sensations in the viewer through geometric precision and perceptual ambiguity. From the late 1960s onward, her introduction of colour transformed her practice, producing works of extraordinary chromatic complexity that remain rooted in the same fundamental inquiry into how the eye perceives form and light.

Market Performance

Riley is one of Britain's most consistently collected living artists, with a robust secondary market anchored by major international auction houses. Her works regularly appear in Christie's, Sotheby's, and Bonhams sales, with significant paintings and prints achieving six-figure results. Riley's limited-edition prints — produced in close collaboration with respected publishers including Karsten Schubert and Waddington Custot — are particularly accessible entry points for new collectors, while her large-scale paintings command substantial premiums. Demand is strong across Europe, the United States, and Asia.

Museum Collections

Riley's work is held by the Tate (London), the Museum of Modern Art (New York), the British Council, the Arts Council of England, the Albright-Knox Art Gallery, the Kunstmuseum Basel, the National Gallery of Australia, and numerous other major institutions worldwide.
