CIE Delta E 94
The CIE Delta E 94 is an improved color difference metric based on
the CIE
Delta E 76 metric. It modifies the delta E value such that
Chroma and Hue differences have a reduced contribution to the
overall delta E for higher Chroma colors.
Since it is based on L*a*b* space, a reference white needs to be
chosen to compute this Readout value.
