Yes, in general colors aren't a good mechanism to indicate permissions.
I prefer to highlight portions of the permissions string,
which is more direct and obvious. See http://www.pixelbeat.org/scripts/l

But we have to be a bit careful adding to the permissions string,
for compat reasons etc. I do like the idea of ^ (hat) => cap.
You could even be fancy and use combining hat (\u0302) so
as to not take up any more place, though combining char support
is not currently supported well enough to allow that I think.

We'll consider it,
thanks,
Pádraig.
