Sliding Hues & Illusory Motion

by Gianni A. Sarcone and Marie-Jo Waeber

In addition to its powerful expressive qualities, color creates the sensation of space and influences the perception of motion...

onstant changing of color or illumination can induce a dramatic feeling of illusory motion*. Look at the center of the 'animated' image below... It represents a cube made of colored elliptic shapes whose sides seem to expand or to shrink according to the color of the background. The

direction of the apparent motion is also determined by the luminance of the edges of the elliptic shapes. In this case, dark colors (red, purple) in the background 'attract' the dark edges of the shapes to the center; while light colors (yellow, green), drive away the light edges from the center.

Conclusion: a progressive or regressive hue sliding of any static image can produce a spatial visual impression.

*illusory motion is used to define the appearance of movement in a static image.
