Car Customization (Flash Game) Problem

I’m currently making a car customization flash game, i’ve already done the coloring part (while user click “Red”, the car become “Red”).

The problem is i want to add an animation before changing the color, eg: when user click “Red”, a sprayer is going left to right, and the car become “Red” after that. So i make a movie clip named “Spray”, and i got 5 labels “Red”, “Green”, “Yellow”, “Orange”, “Blue” in following order, i add the movie clip in every label, but it look weird because when user click “Red”, it play the movie clip and become “Red”, after that user click “Orange”, the car will become “Black” (Black is default color of the car) when playing the movie clip. And user click “Green”, it become “Black” again before changing to “Green”. It always become default color when user choose other colors.

What i want is remain the car’s color when user choose the other color, eg: when user choose “Red”, it play the movie clip first, and become “Red”, after that user choose “Orange”, it play the movie clip and remain “Orange” color in the same time, after that it change to “Orange”, and so on so forth.

Any solution for this? Thanks
