Graphics.Color.Adaptation.VonKries

Color conversion

convert :: (ColorSpace cs' i' e', ColorSpace cs i e) => Color cs' e' -> Color cs e

This function allows conversion of a color between any two color spaces. It uses a very common VonKries chromatic adaptation transform with Bradford matrix. One of more general functions convertWith or convertElevatedWith can be used for selecting another chromatic adaptation algorithm.
