colour-matching functions (of a trichromatic system)
the tristimulus values of monochromatic stimuli of equal radiant power

Note 1 – The three values of a set of colour-matching functions at a given wavelength are called colour-matching coefficients (formerly spectral tristimulus values).

Note 2 – The colour-matching functions may be used to calculate the tristimulus values of a colour stimulus from its colour stimulus function φλ(λ).

Note 3 – In the CIE standard colorimetric systems, the colour-matching functions are represented by the symbols x ¯ ( λ ), y ¯ ( λ ), z ¯ ( λ ) MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaiqaciWacmGadaGadeaabaGaaqaaaOqaaiqadIhagaqeamaabmaabaGaeq4UdWgacaGLOaGaayzkaaGaaiilaiqadMhagaqeamaabmaabaGaeq4UdWgacaGLOaGaayzkaaGaaiilaiqadQhagaqeamaabmaabaGaeq4UdWgacaGLOaGaayzkaaaaaa@43A9@ and x ¯ 10 ( λ ), y ¯ 10 ( λ ), z ¯ 10 ( λ ) MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaiqaciWacmGadaGadeaabaGaaqaaaOqaaiqadIhagaqeamaaBaaaleaacaaIXaGaaGimaaqabaGcdaqadaqaaiabeU7aSbGaayjkaiaawMcaaiaacYcaceWG5bGbaebadaWgaaWcbaGaaGymaiaaicdaaeqaaOWaaeWaaeaacqaH7oaBaiaawIcacaGLPaaacaGGSaGabmOEayaaraWaaSbaaSqaaiaaigdacaaIWaaabeaakmaabmaabaGaeq4UdWgacaGLOaGaayzkaaaaaa@48AA@

fonctions colorimétriques (d'un système trichromatique) f pl
composantes trichromatiques de stimulus monochromatiques de même flux énergétique

Note 1 – Pour une radiation de longueur d'onde donnée, les valeurs des trois fonctions colorimétriques sont appelées coefficients colorimétriques (anciennement composantes trichromatiques spectrales).

Note 2 – Les fonctions colorimétriques peuvent être employées pour calculer les composantes trichromatiques d'un stimulus de couleur d'après sa courbe spectrale φλ(λ).

Note 3 – Dans les systèmes de références colorimétriques CIE, les fonctions colorimétriques sont représentées par les symboles x ¯ ( λ ), y ¯ ( λ ), z ¯ ( λ ) MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaiqaciWacmGadaGadeaabaGaaqaaaOqaaiqadIhagaqeamaabmaabaGaeq4UdWgacaGLOaGaayzkaaGaaiilaiqadMhagaqeamaabmaabaGaeq4UdWgacaGLOaGaayzkaaGaaiilaiqadQhagaqeamaabmaabaGaeq4UdWgacaGLOaGaayzkaaaaaa@43A9@ et x ¯ 10 ( λ ), y ¯ 10 ( λ ), z ¯ 10 ( λ ) MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaiqaciWacmGadaGadeaabaGaaqaaaOqaaiqadIhagaqeamaaBaaaleaacaaIXaGaaGimaaqabaGcdaqadaqaaiabeU7aSbGaayjkaiaawMcaaiaacYcaceWG5bGbaebadaWgaaWcbaGaaGymaiaaicdaaeqaaOWaaeWaaeaacqaH7oaBaiaawIcacaGLPaaacaGGSaGabmOEayaaraWaaSbaaSqaaiaaigdacaaIWaaabeaakmaabmaabaGaeq4UdWgacaGLOaGaayzkaaaaaa@48AA@
