[UDK Frontend] Buttons color

[]Innuendo[]

Hello,

I am making a menu with UDK Frontend, I'd like to change the color of the buttons (from Mouse Over : red to blue),
I didn' find where I can do it (in udk_asset.fla, udk_manager.fla, udk_mainmenu.fla...), does somebody knows where I can find it ?

Thanks

I still get nothing for the launcher.
I was not completely clear : whith the mouse, when we go from a button to another (bellow or above), the following button
is displayed in red for a short time. I'd like to change that color to another (blue).

I searched in related Action Script and Unreal Script file but without success
