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.

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.

Hewitt Crane

Hewitt D. Crane (1927–2008) was an American engineer best known for his pioneering work at SRI International on ERMA (Electronic Recording Machine, Accounting), for Bank of America, magnetic digital logic, neuristor logic, the development of an eye-movement tracking device, and a pen-input device for computers.
