Sorry, I can't help you with latex, but if you can work with a pdf file, 
then ConTeXt seems to handle colors fine. To get just a blue square root 
symbol, you can use



label(\sometxt{$\color[blue]{\sqrt{\color[black] 2}}$},(0,0));


You need to have both ConTeXt and ruby installed. Compile this with
texexec <filename> and it will give you a pdf file.

So you can generate your figures through context, and include the 
resulting pdf file in the latex document.
