About this work

Bridget Riley’s Intervals series represents a nuanced exploration of rhythm, repetition, and the subtle shifts that define visual experience. In this series, Riley arranges vertical bands of color in carefully measured sequences, each one slightly different from the next. The spacing, width, and color of the bands change incrementally, creating a sense of flowing movement across the canvas. Through these slight variations, Riley achieves a striking optical effect, where the eye naturally follows the pattern, responding to the shifts in rhythm and tone that seem to pulse and ripple with energy. Color is essential in the Intervals series, as Riley employs a range of hues that transition seamlessly across each composition. She selects shades that interact in surprising ways, allowing colors to merge, contrast, and reverberate with one another. The soft, harmonious gradations in the series generate a feeling of depth, as if the bands are moving in and out of focus. This creates an immersive visual experience where the bands seem to shimmer or breathe, inviting the viewer into a contemplative state, as their gaze moves across each gentle transition.In the Intervals series, Riley captures the power of subtlety, showing how small, deliberate adjustments can create complex visual sensations. By limiting the elements to bands of color and measured spaces, she invites viewers to focus on the nuances of tone and interval, underscoring the interplay of perception and memory. Each piece within the series evokes an organic sense of rhythm, as if one were experiencing the ebb and flow of music or nature’s cycles. This series reaffirms Riley's dedication to studying the dynamics of visual perception, with each work embodying her skill in crafting art that is both minimalist in form and rich in sensory impact.

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.
