How do I ....randomly change background color?

Hello all,

Is there a way to randomly change the background color on my game? For example; Every 10 seconds, the background color of my game changes to one of six colors.

I know how to randomize a sound using 'choose' but cant see how to randomize a layers background color.

Thanks in advance.
