A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore is a region in the molecule where the energy difference between two separate molecular orbitals falls within the range of the visible spectrum. Visible light that hits the chromo… Webchro·mo·phore ( krō'mō-fōr ), 1. The atomic grouping on which the color of a substance depends. 2. A target tissue for laser light therapy; absorption wavelength of tissue determines choice of laser wavelength. Common dermal chromophores include hemoglobin, oxyhemoglobin, collagen, beta-carotene, and melanin.
