Colour and mathematics

20130902-115335.jpg Although not specifically about colour, this post is a fascinating example of the link between colour science and mathematics.

The four colour theorem uses colour to illustrate a maths topic visually. Interestingly, colour science works the other way around, using mathematical equation to quantify colour. One may argue colour is not an exact science in certain applications, and indeed this is so. However, the maths behind colour science allows one to use a combination of data and visual assessment to reach a reasonable conclusion.

Most important, the four colour theorem makes one think laterally: colour = maths, maths = colour, which is why we love it..
