Nice article on Colour theory and the subtle meaning of colour and how to use it effectively in website design, from Smashing Magazine.
I’ve been thinking about a re-design of this site which is how I stumbled across this article, still not sure what direction to go with the colours for the site though. At the moment I like the idea of a minimalistic black & white theme.
If you’ve got the time you should poke around the rest of the Smashing Magazine site, there are quiet a few nice articles on there.
