Colour theory for designers by Cameron Chapman in 3 parts at smashingmagazine.com. It is written for web designers, but design is design, rules are the same for all. Easy to understand, great examples. About 20% of information is not new for us, we have got it in our student’s binders, but the rest 80% deserve an attention.
I just said about my favorite colourlovers.com, but there are 9 more! 10 Super Useful Tools for Choosing the Right Color Palette at webdesignledger.com. I checked out only kuler yet and love it.
Well, I am getting back to my projects now, deadline is coming. 
Thank you for sharing all these tips! I’m only on Mod1 and I hope to share my tips at some point in the future too. I’ve been using Kuler to check on the color palette balance for the Concept Boards – great tool.
