1. A computer-implemented video decoding method, comprising:
reconstructing a plurality of luma samples associated with a picture; and
reconstructing a chroma block associated with the picture,
wherein reconstructing the chroma block comprises:
determining whether the chroma block has non-zero residues; and
in response to a determination that the chroma block has one or more non-zero chroma residues, determining an averaged value of the plurality of reconstructed luma samples, and scaling residues of the chroma block based on the averaged value, prior to reconstructing the chroma block.
