latin: order cmy colours by sound similarity

Instead of sorting by hue (like RGB) or mnemonic (like Chromacons)
invent a new encoding where letter differences (voice, place, etc)
match colour differences (hue, intensity).  Best effort as letters
do not fit 3 dimensions and sounds differ by language.
