delta E94G
Takes two CIELAB values and calculates color difference (dE) using CIE1994 formula for the graphic design application (kL = 1, k1 = 0.045, k2 = 0.015). NOTE: both CIELAB values must share the same reference white. If they do not: convert to XYZ, adapt, convert back to CIELAB before calculating dE.
Return
delta E (1994) value
Parameters
lab1
First CIELAB value (element order L, a, b)
lab2
Second CIELAB value (element order L, a, b)
