Thanks for the info regrading actions, that would be the second way I outlined above. Good enough for now. As I pointed out earlier, hard coding would not be preferable. I do think, though, that the...

I apologize again, the example was badly chosen. There is the 'vizact.fadeTo()' method to perform this color transition.

Sorry for necroing this old thread. I did not want to create a new one on the same topic.
