5. Chromatic Syntax

    The potency of simply changing the surrounding color becomes apparent in the following examples.
 

Example 5a1:

    This image is similar to demonstrations published by Josef Albers in Interaction of Color. The two orange discs are the same color, but the different surround colors "push" the orange in opposite directions so the discs appear to be two different colors.
 

    Animating the color demonstration alters the emphasis. You may forget that the disc is changing appearance and be more engaged by the effect of changing hue and value contrasts.

    Two more examples are provided below. While viewing the animations, try locking your gaze in a fixed position on the screen to allow the colors to be painted on the retina. To prove that the object is not changing color, a card with a hole cut in it can be placed over the animated image.
 

Example 5a2:

Example 5a3:

    This example is less dramatic than the previous two because the value of the surround is always higher than the object, so it relies on hue pushing only, not value pushing.
