WPF Color interpolation

Question

I am trying to paint a WPF control\'s background based on a palette where each color has been assigned with values (e.g. Red = 0, DarkGreen = 10, Green = 20,LightGreen =30)

Answer 1

I think you'll be better of using a value converter, just take one of the interpolation functions suggested in the other answers and put in in a value converter, use this converter to bind the background property to the value and you're done.
