Webin the a b plane provides a correlate for perceived chroma. The CIELAB color space is intended to allow computation of perceptually meaningful color dierences numer-ically. Speci cally, with respect to a standard color with CIELAB values L s, a s, b s, a sample color with CIELAB values L , a , b is said to have a lightness dierence L = L L WebWhile CIELAB (L*a*b*) uses Cartesian coordinates to calculate a colour in a colour space, CIELAB (L*C*h) uses polar coordinates. This colour expression can be derived from CIELAB (L*a*b*). The L*, as before defines lightness, C* specifies chroma and h denotes hue angle, an angular measurement. The L*C*h expression offers an advantage over …
