that color @ clipping point/gamut boundary in particular color space. channel hits 0 or 255 starting clip @ point.

 

but don't know how much out of gamut. don't know how lower 0 or higher 255 "wants" go.

 

this histogram gives visual clue. if channel solidly backed against low or high end, clipping significant , should consider taking steps remap. proofing target space show histogram space.
