to instead look like this:
"fill: #ff0000 icc-color(blah, 0.0, 1.0, 1.0, 0.0)"
where "blah" is the name of some color-profile that links an .icc file.
*If* software displaying the SVG file supports profiles, then it will
use the icc-color(blah...) part, and will ignore the "#ff0000"
version. Only if displaying software does not support profiles will
it use the "#ff0000". So in that case "#ff0000" is the "fallback" to
be used just in case.
