The author uses CMC I:c (and somewhat incorrectly claims it's also called Delta E, which normally refers to one of the CIELAB metrics). Then he notes the asymmetry of that quasimetric, and a workaround -- averaging the C1,C2 and C2,C1 distances.
I wonder if perhaps he would be better served by simply using the actual "Delta E" metric, specifically ΔE*₀₀, which doesn't have this symmetry problem?
PS. Sexy interactive color matrix table. Small error in the text below -- values >=40 are highlighted, not >45.
- gka 9y agoAuthor here, thanks for the feedback. Well the only thing I know about DeltaE I know from Bruce Lindbloom's website, where he uses the terms interchangably. http://brucelindbloom.com/Eqn_DeltaE_CMC.html http://brucelindbloom.com/Eqn_DeltaE_CMC.html But I'm happy to try out the CIELAB deltaE as well. I can already see another dropdown for comparing difference metrics coming up :) Will fix the text error you found. --edit: after reading again I see that he used DeltaE as a sort of broader category. worth fixing as well
