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).
English: This is a CIE 1931 chromaticity diagram, overlaid with outlines of the color gamuts of sRGB, DCI-P3, Rec2020, AdobeRGB, and ProPhoto. Actual colors are only shown for the SRGB gamut; the remainder of the chromaticity diagram has colors dimmed to indicate they are not representable on a standard monitor.
English: CIE 1931 xy color space diagram. Drawn (or rather programmatically generated) from scratch, but the visual design is based on CIExy1931.png by PAR. Major differences: Colors outside the sRGB triangle are clipped toward the sRGB white point, so they have more accurate hues.
The CIE 1931 xy chromaticity space, also showing the chromaticities of black-body light sources of various temperatures, and lines of constant correlated color temperature sRGB gamut plotted in xyY color space (chromaticity + luminosity) Chromaticity is an objective specification of the quality of a color regardless of its luminance.
This SVG diagram contains embedded raster graphics. Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics.
Comparison of some RGB and CMYK color gamut on a CIE 1931 xy chromaticity diagram Following is a list of representative color systems more-or-less ordered from large to small color gamut: A laser video projector uses three lasers to produce the broadest gamut available in practical display equipment today, derived from the fact that lasers ...
