1. A method of processing video data, comprising:
determining, for a conversion between a video slice including a luma parent block and a chroma parent block and a bitstream of a video, whether to split the luma parent block and the chroma parent block into one or more luma blocks and one or more chroma blocks respectively, wherein a mode type of the luma block or a mode type of the chroma block is determined based on a value of a variable, and wherein the value of the variable is derived based on a color format of the video slice; and
performing the conversion based on the determining,
wherein the luma parent block is generated from a luma coding tree block (CTB) based on a luma partition scheme including recursive partition operations,
wherein the chroma parent block is generated from a chroma CTB based on a chroma partition scheme having same recursive partition operations with the luma partition scheme, and
wherein whether the chroma parent block is allowed to be split depends on at least a mode type of the chroma parent block.
