There are more colors than gray...

Bitmap images (only .BMP files currently) can be used as backgrounds to the browser objects on the Control Center. Click the Browse button to navigate to a graphics directory of your choice. 

Use Gradient Background

The Control Center also allows you to chose a starting and ending color and display a gradient of the various shades between them for browser objects. This functionality is only available at color depths greater than 256 colors. Note: there may be some slight banding displayed unless the Control Center is running at 24-bit color depth (or greater). This is normal.

Use Plain Background

Use to disable texture and gradient support. If the system seems abnormally slow after enabling textures or gradients, try disabling them with this option.

Use Default Font in Sections

Uncheck this item and select the Change Font button to bring up a Font dialog. In the font dialog, you can chose from the available fonts on the system for use on the Control Center, including different types, sizes, and colors.
