In http://www.w3.org/ns/ui are some terms for adding to things (classes, or individuals) hints
for user agents as to what color things should be.
The tabulator uses this for things like task priority level in the tracker in the bug pane.

e.g. http://www.w3.org/ns/ui#color

In practice backgroundColor is more useful if you are going to use us
it for text-based UI, as it is more legible than text color.
