1. A method of video processing, comprising:
performing a conversion between a video and a bitstream of the video according to a format rule,
wherein the format rule specifies whether a value of a third syntax element indicating whether a scaling list adaptation parameter set (APS) network abstraction layer (NAL) unit is allowed to include chroma related syntax elements included in an APS is constrained or not based on whether a fourth syntax element at a picture level indicating an APS identifier that a picture refers to is present or not and whether an index of color format is equal to 0 or not.
