Zusammenfassung:	An electronic device may include a display having an array of display pixels. Storage and processing circuitry may generate display data for the display in an RGB input color space. The display may display the display data in an RGBW output color space. Display control circuitry may use sets of predetermined conversion factors to convert display data from the RGB input color space to the RGBW output color space without requiring conversion to a device-independent color space. Each set of predetermined conversion factors may be associated with a color in a set of predetermined colors. Using the sets of predetermined conversion factors, the display control circuitry may convert RGB values in the input color space to RGBW values in the output color space. The display control circuitry may supply data signals corresponding to the display data in the RGBW output color space to the array of display pixels.
