CIE Luv is a linear transformation of XYZ. As such, it does not have the
cube-root compression that CIELab has. Plus, it does not have at its root
the Munsell color system. So, perceptually, it is not better to describe
color differences than, say, CIE xy. dE94 and dE2000 are both 'weigthed'
color differences metrics. Heavily empirical. dE94 has its followers in the
automotive paint industry. dE2000 is the latest fad (don't mean that
derogatively). Keep in mind that many 'standards' and specifications are
still written with dEab -- even in 2008.
