Abstract
Systems and methods are described for using multiple threshold maps for color dithering. An example method may comprise determining a tertiary RGB color. The example method may comprise selecting, using data representing the tertiary RGB color, a dithering threshold map indicating a pattern of alternating threshold values. The example method may comprise selecting, based on the tertiary RGB color and the dithering threshold map, a tertiary color value set comprising a red value, a green value, and a blue value. The example method may comprise mapping, based on the dithering threshold map, the alternating threshold values to a pixel set of a portion of an RGB display. The pixel set may include one or more of a red pixel, green pixel, and/or blue pixel. The example method may comprise activating, based on the tertiary color value set and the dithering threshold map, at least in part, the pixel set.
