All of the other chlorophylls and carotenoids involved in light absorption are referred to as accessory pigments. Another kind of accessory pigment found in some groups of algae and photosynthetic bacteria are the phycobili proteins, which may impart a red or blue color to the cells in which they occur.
All biological pigments selectively absorb certain wavelengths of light while reflecting others. The principal pigments responsible are: 1  Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs yellow and blue wavelengths of light while reflecting green.2  It is the presence and relative abundance of chlorophyll that gives plants their green color.he primary function of pigments in plants is photosynthesis, which uses the green pigment chlorophyll along with several red and yellow pigments that help to capture as much light energy as possible. Other functions of pigments in plants include attracting insects to flowers to encourage pollination.
