Foreground.

It used to be the case that icons normally had 3D appearance and so on,
in which case we obviously couldn't change the colors easily.  Such
icons were normally distributed in some bitmap format.

These days, icons are treated more like glyphs, and the intention is
that they will have colors suitable for the context they are used in.
Such icons are normally distributed as SVG or indeed as TTF files.

See here for some examples:
