I'm pretty sure the issue starts somewhere around https://github.com/ralph-schleicher/rs-colors/blob/master/cie-lab.lisp#L126 where it's calling (white-point ...)
on the ciexyz color (which doesn't have a white point).
Should work now.
(change-class (make-cie-rgb-color 1 0 0) 'cie-lab-color)
==> #<CIE-LAB-COLOR (49.12652f0 118.28679548921406 84.70089723323953) {10073E8F53}>
I'm trying to convert colors to lab (to implement one of these color difference measures), but getting an error when converting:
