How to programatically change base-color of application.

[ViralCipher]

Hello,

I would like the the user to be able to change the base-color of the application using a Ext.Select where the user selects colors from the options. When the color is selected, I want the application's base-color set to that, so the main color of the application is that color. How would I go about doing this?
