Some people have shown interest in my colour links, and want to get in on the colour knowledge. 
http://www.colorjack.com/studio/ - I think it only works in firefox, because it uses clever things that IE can’t handle.
http://www.vischeck.com/vischeck/vischeckURL.php - Simulates colour blindness, well worth checking out if you are using green or red on your sites.
http://www.colourlovers.com/ - A web 2.0 website for people who love colours.
