Flex 4 Change Main Application Background Color at Runtime
===

Is it possible within Flex 4 to change the background color of an `<s:Application>` at runtime? I've seen examples of how to do this with the MX version of the Application component, but not the spark version.

I cannot bind the `backgroundColor` property to a variable and modify that. However, I am thinking that I should use the `styleManager` property of the component to perform this change.

Could anyone explain how to do this?

Thank you for your time.
