Mouseover and press events on button

1

i have a small image which is just the outline and it is a button. when you mouseover it it colours it it. when you mouseout it goes back to the outlines.

i was wondering if anyones knows if it is possible and how to make it that when i click on the image and then mouseout it will leave it coloured in.

thanks

You should have a button inside a movie clip and blabla blaa. Check this :
