About this work

A printed colour plate arranged as a grid of six squares in white, red, yellow, green, blue and deep magenta, each holding a grey dot. The dots appear to shift in tone against their differing backgrounds, illustrating the simultaneous contrast effect. The plate is captioned Simultaneous Contrast, Fig. 27, and refers to page 100, from a 1911 print by Arthur Herbert Church.
