Colour me red

An unexpected, but very welcome, contributor to my recent post on spectral colour was David Briggs, whose excellent website on colour theory, primarily intended for artists, is an invaluable educational tool for us all (or me, at least). I particularly liked his section on colour vision, which shows just what an incredibly sophisticated visual system we enjoy, as well as how disappointingly little of its workings get into the educational curriculum of either arts or sciences. Check out, for example, the set of “illusions” David uses to show how much neurological processing is involved in maintaining our sense of the constancy of colours under different lighting conditions.
