Try using tikz/pgf.

Xecolor provides none of the facilities that I need, most importantly, access
to the HSB color model. It is in no way a replacement for xcolor, but simply
provides a range of colors made accessible through fontspec's \addfonfeature
command.
Sounded promising on the face of it. Thanks for the suggestion.

The following minimum example shows the problem: I would like to generate some
text in random colors and specify the opacity. In the example file below,
either I get black text with opacity of 50%, or random colors at 100% opacity,
or one random color for all the text at 50% opacity. Can I have my cake and eat
it too? That is, can I have random colors *and* control over the opacity?
I'm using MacTeX 2011.
Thanks for any insights.

Howdy,
Don't know if this will help but try using the xecolor package. Note that it's
commands have a different name than the xcolor package though.
Good Luck,
