The Dimensions of Colour (me): New site reviewing fundamental concepts of light and colour, and attempting to make sense of the dimensions we use to describe them.

Handprint (Bruce MacEvoy): Vast site providing the most comprehensive single online source of information on all aspects of colour, light and vision remotely relevant to the artist. MacEvoy"s own speculations are sometimes unconvincing, but he is always scrupulous about distinguishing these from more firmly established material. Unfortunately, MacEvoy seems obsessed with the idea that almost every element of colour theory is useless dogma. Consequently, he does not always draw the threads together to guide the student towards a clear conceptual framework, and some unnecessarily argumentative parts make tedious reading. Nevertheless, strongly recommended.
