A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision.. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).

This color may also be called lavender (floral) or floral lavender to distinguish it from the web color lavender. It is the color of the central part of the lavender flower. The first recorded use of the word lavender as a color term in English was in 1705. [25] Since the color lavender has a hue code of 275, it may be regarded as a light tone ...
As such, color spaces are an essential tool for color reproduction in print, photography, computer monitors, and television. The most well-known color models are RGB, CMYK, YUV, HSL, and HSV. Because the perception of color is an important aspect of human life, different colors have been associated with emotions, activity, and nationality.
English: Color star using the RGB color model Own work based on: Color star-en.svg and An existing RYB image.This model uses names for hues that are uncommon in color theory and do not reflect standard hue naming.
In color theory, the line of purples or purple boundary is the locus on the edge of the chromaticity diagram formed between extreme spectral red and violet. Except for these endpoints of the line, colors on the line are non-spectral (no monochromatic light source can generate them).
This can only be used as a very rough guide, for instance if a narrow range of wavelengths within the band 647–700 nm is absorbed, then the blue and green receptors will be fully stimulated, making cyan, and the red receptor will be partially stimulated, diluting the cyan to a greyish hue.
A color code is a system for encoding and representing non-color information with colors to facilitate communication. This information tends to be categorical ...
