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). Setting Y as luminance has the useful result that for any given Y value, the XZ plane will contain all possible chromaticities at that luminance.
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 resulting BT.709 color space is almost identical to that of the BT.601-6 used by PAL and NTSC, and covers 35.9% of it. [19] It also covers 33.24% of the CIE 1976 u’v’ space [ 20 ] [ 21 ] and 33.5% of the CIE 1931 x y diagram.
