Black is a color [2] that results from the absence or complete absorption of visible light.It is an achromatic color, without hue, like white and grey. [3] It is often used symbolically or figuratively to represent darkness. [4]
Aristotle concludes this explanation of the color black by saying that in the cases where light cannot penetrate deeply results in darkness or what we call black, but darkness itself is not a color but merely the absence of light. Pseudo-Aristotle, de Coloribus 1.2 [2] Light does not have a color but all colors are visible because of it.
Thus in species that have other pigment cell-types, for example xanthophores, albinos are not entirely white, but instead display a pale yellow color. More common than a complete absence of pigment cells is localized or incomplete hypopigmentation, resulting in irregular patches of white on an animal that otherwise has normal coloring and ...
A fictitious color or imaginary color is a point in a color space that corresponds to combinations of cone cell responses in one eye that cannot be produced by the eye in normal circumstances seeing any possible light spectrum. [4] No physical object can have an imaginary color.
Eigengrau (German for "intrinsic gray"; pronounced [ˈʔaɪ̯gŋ̍ˌgʁaʊ̯] ⓘ), also called Eigenlicht (Dutch and German for "intrinsic light"), dark light, or brain gray, is the uniform dark gray background color that many people report seeing in the absence of light.
In additive color models, such as RGB, white is the additive combination of all primary colored lights, and black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, and black results from a full combination of colored inks.
The severity of color blindness ranges from mostly unnoticeable to full absence of color perception. Color blindness is usually an inherited problem or variation in the functionality of one or more of the three classes of cone cells in the retina, which mediate color vision. [2]
