Unfortunately, it's only PostScript Type 3 fonts which can directly  
have multiple colours.

For Type 1 and TrueType and OpenType, it's only b/w / on/off.

This is worked around by using multiple glyphs per character w/ each  
glyph assigned a different colour. Commercial fonts which use this  
technique include Rosewood from Adobe's Wood Type series or David  
Lemon's Copal.

On the bright side, in (La)TeX, once one writes a macro to handle the  
glyph formatting it's easy and automatic to use.

If your font doesn't support that sort of thing you'll need to convert  
the type to paths and manually set the desired fill colours.
