Oh, sorry, I thought you were talking about generating a set of colors.

WRT icons wanting to use shades of particular colors or other things for
highlights, that can be achieved using SVG filters.  I don't believe
that rsvg supports the color map filter today, but fixing that would
probably be better than fixing it on icon theme side of things.  This
should give artists full control of what colors or shades of colors
they're using.  In some cases, this could look bad, but that's what bug
trackers are for ;)
