The static image below is made of 3 layers having each a different subtractive primary color (magenta, yellow, or cyan) blended in ‘multiply mode’…Now, what happens if we alternately overlay the picture above with colored transparent acetate sheets having each an additive primary color (red, green, or blue)?
Static image overlaid with red acetate sheet, which absorbs the magenta and yellow layers and allows the cyan layer to pass through.
Static image overlaid with green acetate sheet, which absorbs the cyan and yellow layers and allows the magenta layer to pass through.
Static image overlaid with blue acetate sheet, which absorbs the magenta and cyan layers and allows the yellow layer to pass through.
The animated GIF below produces an endless animation with just four layers (static image as background + 3 full color layers with multiply mode blending).
Colored lights can also be used instead of colored acetate sheets to create a seamless animation. Stroboscopic primary colored lights have the advantage to blend so that we only perceive a white light. It can be an excellent exhibit for museums or art galleries to show how colors interact and are perceived by our visual system. The animation exhibit consists in a static picture featuring the kinechromatics pattern onto which a projector casts alternately three additive primary colors, as shown in the animated GIF below. Do not hesitate to contact me if you are interested in this art project.
Here is another funny animation, a dancing skeleton, made with the same principle:
