Impossible color

+ Save concept

Impossible colors or forbidden colors are supposed colors that cannot be perceived in normal seeing of light that is a combination of various intensities of the various frequencies of visible light, but are reported to be seen in special circumstances. [1]

Additive color

Additive color is a method to create color by mixing a number of different light colors, with shades of red, green, and blue being the most common primary colors used in additive color system.

Afterimage

An afterimage is an image that continues to appear in one's vision after the exposure to the original image has ceased.

Bastard color

In theatre lighting, a bastard color is a color, typically in a color gel, wherein the predominant color is blended with small amounts of complementary colors; for example, a "bastard orange" gel would produce predominantly orange light with undertones of blue.

Binocular rivalry

Binocular rivalry is a phenomenon of visual perception in which perception alternates between different images presented to each eye.
