I'm being told that the difference is that the formula I'm using (and
Phil Green) calculates the absolute value of delta L, C, and H and
ColorThink Pro, Bruce's website, and apparently the rest of the color
world use the raw value. This would make a difference when encountering
a negative integer. Comparing two data sets (it8/7.4) and calculating
the dE 2000 using both formula results in a different value for about
30% of the patches, though most differences are very small, and this
would likely depend on the data I suppose. I'm wondering if anyone out
there has comments / opinions as to which formula is more technically
correct ...and not necessarily just because everybody else uses it. ;)
