In an example, a method of coding video data includes determining a first index value associated with a first pixel in a block of video data, wherein the first index value relates a position of the first pixel to an entry of a palette of pixel values, determining, based on the first index value, one or more second index values associated with one or more second pixels in the block of video data, wherein the second index values relate the positions of the one or more second pixels to one or more entries of the palette of pixel values, and coding the first pixel and the one or more second pixels of the block of video data.
