If T is the MathType of your data, construct RealTypes
r, g and b, and construct a new TupleType (r, g, b, T).
Construct a Tuple of this type and link to your Display.
Instead of ConstantMaps to Red, Green and Blue, use
ScalarMaps of r -> Red, etc. Then when you want to update
colors, construct a new Tuple (r, g, b, T) and pass it to
setData() of you DataReferenceImpl.

Good luck, Bill
