One of the most significant artists working today, Bridget Riley's dedication to the interaction of form and color has led to a continued exploration of perception. From the early 1960s, she has used elementary shapes such as lines, circles, curves, and squares to create visual experiences that actively engage the viewer, at times triggering optical sensations of vibration and movement. Her earliest black-and-white compositions offer impressions of several other pigments, while ensuing, multi-chromatic works present color as an active component. Although abstract, her practice is closely linked with nature, which she understands to be "the dynamism of visual forces-an event rather than an appearance."
