1. A method for video decoding performed by at least one processor, the method comprising:
obtaining video data comprising a coding unit (CU);
determining whether an adaptive color transform (ACT) flag is signaled based on both of values of a flag of the CU and a tree type of the CU; and

wherein the ACT flag comprises a syntax of at least “act_enabled_flag”.
