I would personally lean more towards complimentary colors than just use brightness values. Here's a page that does some of this: they provide hex values of Hue at 10 degrees of separation and some rules for generating complimentary colors using them: http://www.december.com/html/spec/colorhslhexuse.html I'm sure they generated them with some algorithm - figuring it out shouldn't be too hard once you have all the values. The page also has a lot of links to other color-related pages and such. Here's another good meta resource: http://www.bestwebatlanta.com/resources/colors_colours_atlanta_web_designers ..shtml Jim Davis ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
