dE2000 - More objective color error measurement?

dE2000 - More objective color error measurement?

2006-03-08 by Tom

I made the mistake of starting to write a CIELab class for calculating
dE2000 in order to go back to my previous tests and see how "close"
colors were matching.

It has been mentioned on the web that dE2000 is a much better
measurement of color error than straight delta-E etc.  Subjectively,
does it do a better job of representing the level of difference an
observer can detect on for example a grey ramp vs a highly saturated
region?

I have a truely warped idea which ... I won't post here but need to
explore in order to feel comfortable understanding color management in
a general sense.

CIE2000 has some, shall we say, holes in it. I usually use CIE94 instead of CIE2000, or the older CIE76, when calculating delta-E values for reasons way to obscure for this list.
