I'm sure the code can be improved, but the following functions let you colorize single letters or groups of letters within lyrics.
You can also apply other markup commands to them. (There is an alternate line in "color-syllable" to show where and how you would do this.)
This will only color one letter or group of letters at a time. Do you want to color multiple items in a word?
Anyway, I hope this helps!
