Abstract
An electronic device may have a main display and an ancillary display. The device may also have a backlit keyboard with glyphs. An ambient light sensor may measure ambient light levels. Control circuitry in the laptop computer may adjust the color cast of content on the ancillary display depending on whether the content contains glyphs or other input display content or whether the content contains images, color gradients, or other output display content. Input display content may be matched in color cast to the color cast of the glyphs, which may be determined based on backlight status and/or measured ambient light information. Output content may be color matched to the main display.
