I have an implementation question. I am trying to have a rectangle change color based on the position of four sliders. (Alpha, Red, Green, Blue) I am attempting to use a dependency property to combine all four values, convert them to a brush, and apply the brush to a rectangle. First question is, is it possible to do this with one property? If not, do I need a property for each slider and a property that is accessed each time one of the sliders change?
