I've recently started learning about colour through this website: http://www.handprint.com/HP/WCL/color18a.html
Its pretty in depth and scientific about colour but it still pertains to art and all that. And thats the problem, its a little complicated for a primer and strays off into science a little too much. Not that its a bad thing. Just overwhelming.
Now I'd go the obvious route and pick up something simpler but from what I've read on that page, theres lots of misconceptions about colour and dogma. Such as colour mixing and the entirety of Betty Edwards book on colour (lol, no surprise).
Any other recommendations that I can look to that arent based on old traditional beliefs?
