Color Code Plan Workouts and Repeating Activities

It would be great if we could select different color codes for the entire background of a workout box or even just a rectangle across the top similar to the annotations.
This may not seem like much, but having color coded workout types and labeling really simplifies the view of a packed calendar.

You could even let us color code all Tuesday bikes a certain color or some other method of letting us customize the look of the calendar.
