Great Vox article: "Reading Rainbow." It hasn't been that long ago (Greek and Roman empires) that numbers and letters were considered qualitative as well as quantitative. Rudolf Steiner (Austrian, 1865-1925), the founder of the Anthroposophical Society, made correlations between numbers and color, sounds and tastes.
