I'm in two minds on this. My first instinct was the same as Behdad's: 
that this is a font rendering issue, and not an obvious candidate for 
CSS level authoring control. However, we do expect CSS to be able to 
control colour display of many page elements, including monochrome text.

While I can see the point of John's proposed font-variant-color 
property, I'm actually more interested in possible CSS interaction with 
colour font technologies that enable user-defined colour values for 
polychromatic glyphs. For example, the Microsoft CPAL table spec allows 
for user defined palettes, and CSS seems to me an obvious place to 
provide for author definition of colours.
