Flash Buttons (Up, Over, Down, Hit)

Recently I am feeling like an idiot in Flash with buttons! I think perhaps I am forgetting something about the up, over, down, and hit states.

What I am trying to do is to have the button color change to a different color when it is on the page. The color only changes when I roll over it or hit it.

Once I am on the page it changes back to the color it is on the up state.

Example: http://www.somethingfab.me/ (When you are on the home page the button is red, but when on the about page the home button changes to white to show hierarchy.)
