Valence color

This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.

A valence color is a color that can be perceived by the human eye and is made up of several spectral color stimuli .

Spectral colors are color stimuli from monochromatic light . Valence colors result for human color perception when several spectral colors are superimposed through additive color mixing .

Examples

• Sunlight contains all spectral colors, whereby these spectral components have physiologically roughly equivalent intensity. The perception of sunlight is thus the valence color white .
• The color valence magenta does not appear in the spectrum of visible light , so it is not a spectral color. However, it is a valence color from the mixture of spectral violet and spectral red . Gradations of magenta that do not lie on the purple line can also be created by superimposing blue and red.
