Thought I would mention two tools that help Web designers select colors for a site's theme. Because, as mentioned often at this site - if you get traffic but can not convert the user, its just a waste of bandwidth. Of course, a nasty color scheme might influence a search referral to hit that back button.
Tool number one is named Color Schemes Generator and it is the newer version of tool number two which is now named Color Schemes Generator Old. I wish I could remember exactly where I found this. I am pretty sure it came from Cre8asite Forums and I think the member that posted this was using the username cline (help me out if you know the source).
