A method of decoding video data includes determining that a current block of the video data is coded in palette mode, determining, between single tree or dual tree partitioning, that the current block is coded with single tree partitioning enabled, determining that the current block is coded in monochrome format, when the current block is coded with single tree partitioning enabled and when the current block is coded in monochrome format, determining that a number of color components used for palette mode decoding the current block is equal to one, and palette mode decoding the current block based on the determined number of color components used for palette mode decoding the current block being equal to one.
