Actionscript to tween colours

Hi,

I’m wondering what the actionscript would be to tween between colours in a movieclip. For example, in the sliding menu tutorial { http://www.kirupa.com/developer/flash5/slidingmenu.htm } to have one background clip which tweened between colours as each section slides into view.

Does anyone know how this would be acheived? I’ve looked around but can’t seem to find anything on it …

thanks

K
