For discussion, see:
https://github.com/fiji/fiji/pull/133The main goal is to have black (instead of white) be the first color, while
preserving the other attributes of Glasbey. However, I actually did not
think hard about whether inverting the LUT actually serves that purpose
(qualitatively, adjacent colors seem "less different" to my eye).
Regards,
Curtis
