I love playing with colours. Seeing the effect that two colours have on eachother is very interesting. I have a few books on this subject, but have never gotten very far with them, (a very dry read). It is definitely true that a colour is only as good as the colour next to it. You can mix what you may think is the most beautiful colour in the world, but if you put it beside the wrong colour, it can look like the ugliest colour ever.
