Cream, black and emerald (1972) is a painting of complex, varying, concentric squares, which slot into place. Evocative of tiles in shape and colour, the echoing pattern extends beyond the canvas, evoking limitless space. In this significant early work, she begins to deconstruct the grid – dismantling, cutting, splicing and layering to create an endless set of configurations. Webb is already exploring the formal elements and processes that she will remain dedicated to throughout her career over the next fifty years.
