Stripe colors for taxonomy as well as node type.

All my events are the same node type, but they differ in taxonomy category. I would very much like to be able to display each taxonomy term as a different color stripe on the calendar. My events are all of the same type to give more continuity between them. I think this would be very valuable feature for calendar, especially in the year view where colours distinguish the different days.
If this is not a priority feature, and somebody has a patch to achieve this that would be excellent.
Thanks
