auxochrome
Quick Summary
An auxochrome is a group of atoms within an organic molecule that, when attached to a chromophore, modifies the color of the compound. While chromophores are responsible for absorbing light and thus causing color, auxochromes enhance this effect by shifting the absorption into the visible region of the electromagnetic spectrum.12
Essentially, auxochromes extend the conjugated system of the chromophore, leading to deeper or more vibrant colors. Without auxochromes, chromophores may not absorb visible light. The presence and type of auxochromes influence the specific color observed.2
