In an example a method of processing video data includes determining palette indices of a first row of a block of video data, wherein the palette indices correspond to a palette of one or more colors for coding the block of video data, and wherein the palette indices of the first row include one or more indices that are associated with a color value in the palette and a syntax element that is not associated with a color value in the palette. The method also includes coding a run of palette indices of a second row of the block of video data relative to the palette indices of the first row, wherein the run includes the one or more indices that are associated with a color value in the palette and the syntax element that is not associated with a color value in the palette.
