The energy of the emitted light from the dye is given as 2.3393 eV. To determine the color of light absorbed, one must consider the concept of complementary colors: the color absorbed is opposite to the color emitted. Since the dye emits light corresponding to a certain energy, the absorbed color will be red, as it is the complementary color to the emitted light in the visible spectrum."}
