What color replaces cream or white on the belly scales of a standard Yellow Belly Ball Python?

Bright, often intense yellow

One of the signature visual indicators of the Yellow Belly morph is the dramatic shift in ventral coloration. Where a typical, or normal, ball python displays belly scales that are cream or white, the Yellow Belly expression introduces a significantly brighter hue, often described as bright or intense yellow. This feature is a key distinguishing mark that keepers examine, as it represents a substantial visual upgrade in the snake's aesthetic presentation compared to the standard base coloration. This brightness on the underside is a direct result of the gene's effect on pigment deposition in those specific scales.
