Delta E in its original form (1976 version) suffered from too much simplification of the math in order to ease the computation. Computing was expensive. It also was optimized for what is now considered the "wrong" things; large color differences.

Delta E(2000)is substantially better, giving results that more closely agree with expert visual judgment.

Delta E (cmc) is very good when used by people or machines that understand the variable settings of the tolerancing system.
