Hi Joshua,

I have tried to achieve the same with Arabic. See my posting to this 
list of June 26 (thread: xetexref updated) and Jonathan's reply to it. 
This explains the behaviour you describe, at least for XeTeX.

There is however an extension to ArabTeX which does this correctly, and 
I assume it should be fairly easy to adapt it to colorize Hebrew vowel 
under ArabTeX as well : see
http://ufal.mff.cuni.cz/~smrz/arabtex/acolor.pdf   and
http://sourceforge.net/projects/encode-arabic/
