Abstract: An information handling system keyboard illuminates key values in each of plural keycaps with a backlight located below the plural keys and directed upward through the plural keys and having illumination that adjusts color temperature under management of a controller. A light sensor detects ambient light color temperature and communicates the ambient light color temperature to the controller, which executes instructions in non-transitory memory to adjust the backlight color illumination based on the detected ambient light color temperature to increase color contrast of backlight illumination relative to ambient light and thereby better highlight the key values on the keycap upper surfaces.
