Hi Matzu,
You can transform the RGB values in the color patsches to Lab by using the
'Color Transformer' plugin:
http://rsbweb.nih.gov/ij/plugins/color-transforms.html
<http://rsbweb.nih.gov/ij/plugins/color-transforms.html>
You will get a 3 slice stack with separated Lab values. After this you can
calculate delta E differences by the square root of
((L1-L2)^2+(a1-a2)^2+(b1-b2)^2)
