Green is common in nature, as many plants are green because of a complex chemical known as chlorophyll, which is involved in [[photosynthesis]]. Chlorophyll absorbs the long wavelengths of light (red) and short wavelengths of light (blue) much more efficiently than the wavelengths that appear green to the human eye, so light reflected by plants is enriched in green.<ref>

Chlorophyll absorbs green light poorly because it first arose in organisms living in oceans where purple [[halobacteria]] were already exploiting photosynthesis. Their purple color arose because they extracted energy in the green portion of the spectrum using [[bacteriorhodopsin]]. The new organisms that then later came to dominate the extraction of light were selected to exploit those portions of the spectrum not used by the halobacteria.<ref>

Animals typically use the color green as [[camouflage]], blending in with the chlorophyll green of the surrounding environment.<ref name=brit/> Most fish, reptiles, amphibians, and birds appear green because of a [[reflection (physics)|reflection]] of blue light coming through an over-layer of yellow pigment. Perception of color can also be affected by the surrounding environment. For example, broadleaf forests typically have a yellow-green light about them as the trees filter the light. [[Turacoverdin]] is one chemical which can cause a green hue in birds, especially.<ref name=brit/> Invertebrates such as insects or mollusks often display green colors because of [[porphyrin]] pigments, sometimes caused by diet. This can causes their feces to look green as well. Other chemicals which generally contribute to greenness among organisms are [[flavins]] (lychochromes) and hemanovadin.<ref name = brit /> Humans have imitated this by wearing green clothing as a camouflage in military and other fields. Substances that may impart a greenish hue to one's skin include [[biliverdin]], the green pigment in [[bile]], and [[ceruloplasmin]], a [[protein]] that carries copper [[ion]]s in [[chelation]].

The [[Micrommata virescens|green huntsman spider]] is green due to the presence of bilin pigments in the spider's hemolymph (circulatory system fluids) and [[Interstitial fluid|tissue fluids]].<ref>
