What is the effect of the observer angle on CIELAB values?

CIELAB Color Space. Internationally standardized color systems, like the widely used CIELAB system, combine data of standardized illuminant, standardized ... CIELAB (L*a*b*) and CIELAB (L*C*h) are used to compare the colours of two objects. The expressions for these colour differences are DL*, Da*, Db*, or DL* DC* DH Jan 18, 2021 ... In general, the transfer function in CIELAB is considered close to perceptually uniform, but as always in color perception, the truth is a bit ...
