Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs blue and red wavelengths of light while reflecting a majority of green. It is the presence and relative abundance of chlorophyll that gives plants their green color. All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b.
Gamboge (/ ɡ æ m ˈ b oʊ ʒ,-ˈ b uː ʒ / gam-BOHZH, - BOOZH) [1] is a deep-yellow pigment derived from a species of tree that primarily grows in Cambodia. [2] Popular in east Asian watercolor works, it has been used across a number of media dating back to the 8th century.
Like plants, the cyanobacteria use water as an electron donor for photosynthesis and therefore liberate oxygen; they also use chlorophyll as a pigment.In addition, most cyanobacteria use phycobiliproteins, water-soluble pigments which occur in the cytoplasm of the chloroplast, to capture light energy and pass it on to the chlorophylls.
Pigments for sale at a market stall in Goa, India. A pigment is a powder used to add color or change visual appearance. Pigments are completely or nearly insoluble and chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use.

The xanthophyll pool, or total xanthophyll cycle pigment levels are sometimes abbreviated as "VAZ" in scientific literature. [5] "VAZ" is an abbreviation of the cycle's main pigments in order of lowest to highest photoprotection each pigment provides. Antheraxanthin is denoted by the "A" in the middle, between violaxanthin (V) and zeaxanthin (Z).
Indian yellow is a complex pigment consisting primarily of euxanthic acid salts (magnesium euxanthate and calcium euxanthate), [2] euxanthone and sulphonated euxanthone.

The chemical composition of the compound was determined by powder diffraction in the 1950s [9] and was found to be a composite of palygorskite and indigo, most likely derived from the leaves of the añil. An actual recipe to reproduce Maya blue pigment was published in 1993 by a Mexican historian and chemist, Constantino Reyes-Valerio.
