Change Workspace / User Interface color from Dark to Light?

Hello,

I'm new to AE, but have been using Photoshop / Illustrator for quite a while - and am accustomed to changing the UI from a dark gray to a lighter color.

How do you change the Workspace / UI in After Effects CS6 from the default dark gray to a lighter gray?

I checked the Preferences FAQ before posting, but couldn't isolate the option.

Thanks
