It is. Absorption of visible light is due to the formation of an intramolecular charge transfer complex in which the rhodanine ring part serves as an electron acceptor and the quinoline group serves as an electron donor. That is, when the π electrons delocalized in the electron donor in the ground state are transferred to the empty orbit of the electron acceptor through the group r=C=CH-CH=J, light energy is absorbed and color is generated.
