Simultaneous Contrast

Simultaneous Contrast (colours taking on characteristics of their complement) is occasionally overridden by the Spreading Effect. This occurs regularly when there is a difference in the "spatial frequency" of objects on a background. After analysing the diagram below, you will see how this tactic can be applied to the design of tapestries in order to preserve certain colour sensations.

Instructions:

Look at the two sets of grey patches occupying the same area space on the light red background. Notice that the patches on the left appear slightly greenish. On the right, the grey patches definitely tend towards red. Simultaneous contrast is taking place on the larger blocks of the neutral grey. Whereas, the thinner strips of grey exhibit"spreading."
