Colour Theory

Following my visit to the Monet Exhibition at Te Papa, my interest in art has been revived. Ifeel stuck art-wise because I really love colour, but want to be able to draw well before I get into painting. So I am workign on my drawing, and also doing some reading around colour.
Today, my To Do List told me to investigate colo(u)r theory and I have spent a happy half hour exploring the following websites.

1. Artyfactory has a rainbow theme to its colour scheme and offers lessons on colour theory and colour terms. A good starting place for beginners.
2. Color Worqx is a more academic approach, and more subtly coloured.
3. The luminous landscape - use of colour theory in landscape photos.
4. Color Matters offers a lot more than I have so far explored, but has the basic colour theory well-covered.
