Claim 0:
1. A method of processing video data, comprising:
performing a conversion between a current video block of a video and a bitstream of the video,
wherein when the current video block is coded using a colour transform mode, the conversion comprises applying an inverse colour transform on the current video block according to a rule,
wherein the rule specifies that a clipping operation, f(a, b, x), is applied to an input of the inverse colour transform,
wherein f(a, b, x)=(x<a?a:(x>b?b:x)), x is a value to be clipped, a is an integer lower bound of the clipping operation, and b is an integer upper bound of the clipping operation,
wherein a=−(1<<(BitDepth+K)) and BitDepth is a bit depth of the current video block,
wherein b=(1<<(BitDepth+K))−1, and
wherein K is a non-zero integer.
