The Sikkens Foundation has described Riley's use of colour as "a sensational oeuvre from which a new generation of artists is drawing inspiration". The Gemeentemuseum exhibition includes a new 20 metre (65 foot) wall mural, painted by assistants, entitled Composition with Circles 9.

Bridget Riley since the mid-1960s is known for her distinctive, optically vibrant paintings, called coined “Op Art.” She explores optical phenomena and juxtaposes color either by using a chromatic technique of identifiable hues or by selecting achromatic colors (black, white or gray). In doing so, her work appears to flicker, pulsate and move, encouraging the viewer’s visual tension. Riley’s vibrant optical pattern paintings, which she painted in the 1960s, were hugely popular and become a hallmark of the period. As your eyes explore the picture to the left, can you continue to see momentary afterimages (white dots) that cause a slight flickering effect?
