This thread shows blatant ignorance on the topic of color spaces when people try do bend alpha/occlusion and non-linear gradient together. I don't assume, I just read.

> Your claim that their sole reason for existing is to calculate deltaE is incorrect. They are used for many other purposes such as gamut mapping or the creation of perceptually even color scales or the creation of perceptually even color harmonies, to mention a few.

Which are only Delta E applied as a numerical minimizer of visual error while doing color mapping. It's still Delta E. It's only Delta E all the way, otherwise they wouldn't have bothered to make 3D euclidean spaces where color differences are the euclidean norm.

I truly hope they didn't forgot to support Microsoft IE 8 in their standard. Everyone needs broken technology, especially when it's opensource and the whole industry relies on it.
