Method for determining dE values

What method does Color Think use to determine dE values in the deltaE colors window?

CMC 94?
Delta E 2002?

The current version of ColorThink uses dE76, the standard euclidean 3D distance calculation. That also corresponds to the vector length in the graph.

ColorThink Pro will allow dE76, dE94, CMC 1:1, CMC 2:1 and dE2000



Welcome back Steve!

Thank you for the information. There’s been some discussion with the vendor who supplied the proof, and he says coordinate X to Y is ##dE… and I’m coming up with a different value!

That explains a lot, thank you again, Steve.
