It is a molecule or functional group which give colour to the compound.
Its a molecule that is absored by exsiting an electron from ground state to a higher excited state, in the range of a visible spectrum
functional group imparting colour to a compound,
t is an atom or functional group , whcih is responsible to produce colour in colorless compound. they have Multiple bonds of -ene,-yne, and carbonyl groups in which the electrons are more loosly bond than those in fully saturated compounds.

chromophore is functional group which is responsible to exhibit color.
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 chromophore can thus be absorbed by exciting an electron from its ground state into an excited state.
