Molecule structures {chromophore} determine color. For example, retinal visual pigment molecules have chromophore group. Hydroxyl, amine, and halogen groups do not make UV or visible light, but they can affect nearby-chromophore intensity or wavelength. However, groups separated by two single bonds do not affect each other.
