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 The L*C*h color space is similar to L*a*b*, but it describes color differently using cylindrical coordinates instead of rectangular coordinates.
