The length of carotenoids also has a role in plant coloration, as the length of the polyene tail determines which wavelengths of light the plant will absorb. Wavelengths that are not absorbed are reflected and are what we see as the color of a plant. Therefore, differing species will contain carotenoids with differing tail lengths allowing them to absorb and reflect different colors.
