1. A method comprising:
obtaining an input image and a color palette;
generating, using the color palette, a first reduced-color image by projecting the input image into a color space represented by the color palette;
applying the input image and the first reduced-color image to an encoder to generate a dithering image; and
generating, using the color palette, a second reduced-color image by projecting a combination of the input image and the dithering image into the color space represented by the color palette.
