CIEDE2000 is the most recent in a series of color difference formulas. It has become the standard color difference formula, despite two of its shortcomings. The first shortcoming is that it does not have an associated color space. The second shortcoming is that it is a very complicated formula. This ongoing work addresses both of these issues. The final goal is to provide a color space where color differences very similar to CIEDE2000 can be computed using the Euclidean distance formula, and where the calculations are significantly simpler.
This paper provides an alternative for the L* value, introducing a much simpler computation that is a quite serviceable approximation to DE00 color differences in the L* direction. This is called L00.
