A method for decoding a video sequence of a coded video stream, performed by at least one processor, using at least one color palette in a palette mode, each of the at least one color palette including at least one luma value or at least one chroma value, the method including determining whether a current tree structure is a dual tree structure where a luma color plane has a split tree structure that is different from a split tree structure of a chroma color plane; and decoding at least one image of the video sequence using one or more color palettes of the at least one color palette based on the determining whether the current tree structure is the dual tree structure.
