A system and method for setting themes automatically on computing devices having backlit LED surfaces is disclosed. The system extracts the main or dominant color palette out of the wallpaper that the user sets and uses that palette to lightly customize system UI. The system thus automatically selects the theme to match the user's choice and applies this to various system interfaces such as menus, applications or other operating system screens. For devices with keyboards that have LED backlight and devices that have a touch keyboard, the method envisages use of multi-colored LEDs. The system would adjust colors of the LEDs based on the extracted color palette to harmonize the user's wallpaper choice, system UI, and the hardware, to provide the feel like they are meant to work together.
