Christian Faur uses a color alphabet in his art. He’s used it in these striped paintings, where each stripe is a letter (thickness connotes the duration of the letter in the word, and white denotes the end of a word). First the key, then a close up of “Rules Can Create Artwork” and then several of the works on the wall I saw at the Kim Foster Gallery. The theory behind the color choices is described here. Also check out how he uses the alphabet to make portraits from crayons here.
