Changing color with actionscript

Hi there

I’ve seen the tutorial on changing colours randomly with a button press but I was wondering if there was something slightly different available to help me.

I want to click on a button and have certain elements onscreen transition to a specific colour over the space of 2 seconds approx. the basic idea is to be able to skin the site and pick the monochromoatic colour scheme.

Can anyone help me out with this?

thanks much for any input!!
