1. A method of processing video data, comprising:
performing a conversion between a video comprising a video block and a bitstream of the video according to a rule,
wherein the video block is a coding tree node that includes one or more coding blocks, and
wherein the rule specifies that one or more of the following coding modes are allowed to be used by one or more luma blocks of the one or more coding blocks: an intra prediction coding mode, an intra block copy (IBC) mode and a palette coding mode, and wherein the intra prediction coding mode is applied to one or more chroma blocks of the one or more coding blocks when a local dual tree is applied to the one or more coding blocks inside the coding tree node;
wherein the rule specifies that multiple luma blocks inside the coding tree node are allowed to be coded, in a mixed manner, with more than one coding modes of the intra prediction coding mode, the IBC mode, and the palette coding mode, and wherein the more than one coding modes comprise any two or more of the intra prediction coding mode, the IBC mode, and the palette coding mode.
