No, I hadn't tried using the Munsell color system, but I had tried CIEXYZ, CIELAB, CIELUV, and gave a brief glance at CIECAM. All 4 of those color systems are designed based on scientific measurements of perceived colors. If there were more reasons to try it, I might be more motivated, but the only disadvantage to my stepping algorithm is that it can't work if the color palette doesn't follow the same general format as xterm's... and every color palette I've found so far does. ~Matt --~--~---------~--~----~------------~-------~--~----~ You received this message from the "vim_dev" maillist.
