Abstract: An electronic device includes an adjustable RGBW front light. The electronic device additional includes circuitry configured to determine if a transition between phases has occurred, the phases being based on a time of day, automatically display a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, and automatically adjust a predetermined mixture of light to be displayed via the adjustable RGBW front light such that the predetermined screen color temperature does not change in response to a change in a brightness level of the electronic device.

Abstract: An electronic reading device can include an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device can include circuitry configured to determine if a transition between phases has occurred, wherein the phases include a night phase, a sunrise transition phase, a daytime phase, and a sunset transition phase, automatically display a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, determine if a brightness level has changed, and automatically adjust a predetermined mixture of light to be displayed via the adjustable RGBW front light such that the screen color temperature does not change in response to the changing brightness level.
