Abstract
An electronic device such as a desktop computer or other device may have an electronic device housing with front and rear faces. A display may be mounted on the front face. The electronic device may include multiple ambient light sensors such as a front color ambient light sensor on the front face and a rear color ambient light sensor on the rear face. The front ambient light sensor gathers a front ambient light intensity measurement and a front ambient light color measurement. The rear ambient light sensor gathers a rear ambient light intensity measurement and a rear ambient light color measurement. During operation, control circuitry in the electronic device takes action based on data from the ambient light sensors. The control circuitry may adjust a white point of the display using a combined color value that is produced using a combining function.
