I'm confused here.

I thought this discussion was about use of a color profile for
conversion of input colors specified in CSS.  But this requirement
sounds like you're talking about conversion of colors to the color
space of the output device.

Which one is it?

Color matching to images sounds again like conversion of input
colors.  But I guess I don't understand what you mean by "print
specific color profiles".
