Hello

Lets say Im making a site for a car and the car comes in four different colors.  
I then whant to have four buttons, red, blue, silver and black. When you click the black one I want the car to change color to black with a animation, color runing down the car until its covered.(mask animation) This is not so hard but if a push the black one when the car is already black I dont want the animation to play all over again, just stay black. But if I click red I want red color runing down over the black etc…

What is the best way to do this?
