Auxochrome

In organic chemistry, an auxochrome (from Ancient Greek αὐξάνω (auxanō) 'increase' and χρῶμα (chrōma) 'colour') is a group of atoms attached to a chromophore which modifies the ability of that chromophore to absorb light. They themselves fail to produce the colour, but instead intensify the colour of the chromogen when present along with the chromophores…
