# UIColorName

The name of a color to use as the background color on the launch screen.

## Discussion

Provide a value for this key that’s the name of a color in your asset catalog. You use the same string for the value that you might use when calling the <doc://com.apple.documentation/documentation/UIKit/UIColor/init(named:)> initializer of <doc://com.apple.documentation/documentation/UIKit/UIColor>.

If you don’t set a color, the system uses a default of <doc://com.apple.documentation/documentation/UIKit/UIColor/systemBackground>, which varies according to whether the user has selected the light appearance or Dark Mode for the device.
