Color matching in the textile dyeing industry is essential. In this branch, three types of metamerism are commonly encountered: illuminant metamerism, observer metamerism and field-size metamerism. [citation needed] Due to the wide range of different illuminants in modern life, textile color matching is difficult to ensure. Metamerism on large ...
The opponent color theory suggests that there are three opponent channels: Red versus green; Blue versus yellow; Black versus white (this is achromatic and detects light–dark variation or luminance) [3]
Achromatic grays are colors between black and white (without chroma). Chromatic grays can be thought as achromatic grays mixed with warm hues such as yellow (warm grays) or cool hues such as azure (cool grays). This gray color template includes both achromatic and chromatic grays.
Any color that lacks strong chromatic content is said to be unsaturated, achromatic, or near neutral. Pure achromatic colors include black, white, all grays and beiges; near neutrals include browns, tans, pastels, and darker colors. Near neutrals can be of any hue or lightness.
Helmholtz–Kohlrausch effect has been described in mathematical models by Fairchild and Pirrotta 1991, Nayatani 1997, and most recently High, Green, and Nussbamm 2023. Given a color's CIELAB coordinates, these methods produce an adjusted "equivalent achromatic lightness" L* EAL, i.e. the shade of grey humans think is as bright as the color. [5]
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).

Achromatic means literally “without color”. It may refer to: Achromatic colors, “greys” or “neutral colors”, also black or white; Achromatic lens, a lens designed to minimize chromatic aberration; Achromatic vision: Monochromacy (total color blindness) Achromatopsia; Monochrome (disambiguation)
