Works in the extreme case, but it gets shaky in the middle values unless you're using the greyscale palette: cyan = color(#rgb, 0, 255, 255) dkcyan = color(#rgb, 0, 204, 255) dkbrn = color(#rgb, 51, 0, 0) -- System - Win palette put cyan.paletteIndex -- 1 put dkbrn.paletteIndex -- 179 put dkcyan.paletteIndex -- 184 -- System - Mac palette put cyan.paletteIndex -- 180 put dkbrn.paletteIndex -- 179 put dkcyan.paletteIndex -- 186 -- Greyscale palette put cyan.paletteIndex -- 85 put dkbrn.paletteIndex -- 238 put dkcyan.paletteIndex -- 102 -- Carl West [EMAIL PROTECTED] http://eisen.home.attbi.com I have no superfluous leisure; my stay must be stolen out of other affairs; but I will attend you awhile. - Isabella, Measure for Measure, Act 3 Scene 1 - [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]).
