Gamut of the CIE RGB primaries and location of primaries on the CIE 1931 xy chromaticity diagram The CIE 1931 RGB color matching functions normalized to equal areas under the curves. Multiplying the red and green curves by 72.0962 and 1.3791 respectively yields the actual color matching functions.

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.
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.
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.
PDF version of the chart. The colors of the chart were described by McCamy et al. with colorimetric measurements using the CIE 1931 2° standard observer and Illuminant C, and also in terms of the Munsell color system. Using measured reflectance spectra, it is possible to derive CIELAB coordinates for Illuminants D 65 and D 50 and coordinates ...
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 .
The primary colors are usually mapped to xyY chromaticity coordinates, though the uʹ,vʹ coordinates from the UCS chromaticity diagram may be used. Both xyY and uʹ,vʹ are derived from the CIE 1931 color space, a device independent space also known as XYZ which covers the full gamut of human-perceptible colors visible to the CIE 2° standard ...
