CIE 1976 uniform-chromaticity-scale diagram
CIE 1976 UCS diagram
the uniform-chromaticity-scale diagram produced by plotting in rectangular coordinates v′ against u′, quantities defined by the equations

{ u = 4X X+15Y+3Z = 4x 2x+12y+3 v = 9Y X+15Y+3Z = 9y 2x+12y+3 MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=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@6307@

X, Y, Z are the tristimulus values in the CIE 1931 or 1964 standard colorimetric systems, and x, y are the corresponding chromaticity coordinates of the colour stimulus considered

Note – This diagram is a modification of, and supersedes, the CIE 1960 UCS diagram in which v was plotted against u in rectangular coordinates. The relationships between the two pairs of coordinates are :

u′ = u; v′ = 1,5v.

X, Y, Z sont les composantes trichromatiques dans les systèmes de référence colorimétriques CIE 1931 ou 1964 et x, y les coordonnées trichromatiques correspondantes du stimulus de couleur considéré

Note – Ce diagramme remplace en le modifiant le diagramme de chromaticité uniforme CIE 1960 dont les coordonnées rectangulaires étaient u et v. Les relations entre ces coordonnées et les coordonnées actuelles sont:

u′ = u; v′ = 1,5v.
