The Six-Color Alphabet was invented by David Kelley as an alternative alphabet for English. There are two versions of the alphabet: one is a simple substitution system for English letters; the other uses a more phonemic approach.
David created this sample as an art project entitled "Navajo-like 'Talking Blankets'" for some Japanese friends.
