chromogen
Pigment-forming compound
A chromogen is a substance that can be converted into a pigment or dye, typically through chemical reaction or oxidation.
In biology and histology, chromogens are colorless compounds that produce visible color when acted upon by enzymes, making them essential for staining tissues and detecting specific molecules: The chromogen turned blue in the presence of the antibody.
