1. A method of decoding video data, comprising:
deriving a plurality of variables associated with a coding unit, wherein the plurality of variables indicate a luma coding block size and a coding tree type;
determining a palette mode block size threshold for the coding unit in accordance with the coding tree type;
at least in accordance with a determination that the luma coding block size is greater than the palette mode block size threshold:
receiving, from a bitstream, a palette mode enable flag associated with the coding unit; and
decoding, from the bitstream, the coding unit in accordance with the palette mode enable flag.
