A variant or older term for chromogen; a substance capable of producing or generating color.
From Greek 'chroma' (color) and 'gen' (to produce), this is an alternative form used in older scientific literature, particularly in European scientific traditions.
The difference between 'chromogen' and 'chromogene' is mostly historical—scientists gradually standardized the terminology, just like how 'gaol' became 'jail' in English spelling conventions.
