Plants, in general, contain six ubiquitous carotenoids: neoxanthin, violaxanthin, antheraxanthin, zeaxanthin, lutein and β-carotene. Lutein is a yellow pigment found in fruits and vegetables and is the most abundant carotenoid in plants. Lycopene is the red pigment responsible for the color of tomatoes.
How does pigment color differ from structural color?
Pigment color differs from structural color in that it is the same for all viewing angles, whereas structura l color is the result of selective reflection or iridescence, usually because of multilayer structures.
Why do sponges have color patterns?
It's known that animals use their color patterns to warn off predators, however it has been observed that a sponge pigment mimicked a chemical which involved the regulation of moulting of an amphipod that was known to prey on sponges. So whenever that amphipod eats the sponge, the chemical pigments prevents the moulting, and the amphipod eventually dies.

How are color pigments produced?
They are produced due to color absorption by a particular living organism from its environment. Different organisms absorb different wavelengths of light and this results in the variations that are found in color pigments.

Historic and Prehistoric Pigments
Dye and Luminescence
- A pigment is a substance that is either dry or else insoluble in its liquid carrier. A pigment in liquid forms a suspension. In contrast, a dye is either a liquid colorant or else dissolves in a liquid to form a solution. Sometimes a soluble dye may be precipitated into a metal salt pigment. A pigment made from a dye in this manner is called a lake pigment(e.g., aluminum lake, indigo lak…
Pigment Definition in The Life Sciences
- In biology, the term "pigment" is defined somewhat differently, where a pigment refers to any colored molecule found in a cell, regardless of whether or not it is soluble. So, although hemoglobin, chlorophyll, melanin, and bilirubin (as examples) don't fit the narrow definition of pigment in science, they are biological pigments. In animal and plan...
How Pigments Work
- Pigments selectively absorb wavelengths of light. When white light strikes a pigment molecule, there are different processes that can lead to absorption. Conjugated systems of double bonds absorb light in some organic pigments. Inorganic pigments may absorb light by electron transfer. For example, vermilion absorbs light, transferring an electron from the sulfur anion (S2 …
List of Significant Pigments
- Pigments may be classified according to whether they are organic or inorganic. Inorganic pigments may or may not be metal-based. Here is a list of some key pigments:
Overview
Biological pigments, also known simply as pigments or biochromes, are substances produced by living organisms that have a color resulting from selective color absorption. Biological pigments include plant pigments and flower pigments. Many biological structures, such as skin, eyes, feathers, fur and hair contain pigments such as melanin in specialized cells called chromatophores. …
Biological pigments
See conjugated systems for electron bond chemistry that causes these molecules to have pigment.
• Heme/porphyrin-based: chlorophyll, bilirubin, hemocyanin, hemoglobin, myoglobin
• Light-emitting: luciferin
Pigments in plants
The primary function of pigments in plants is photosynthesis, which uses the green pigment chlorophyll and several colorful pigments that absorb as much light energy as possible. Pigments are also known to play a role in pollination where pigment accumulation or loss can lead to floral color change, signaling to pollinators which flowers are rewarding and contain more pollen and nectar.
Pigments in algae
Algae are very diverse photosynthetic organisms, which differ from plants in that they are aquatic organisms, they do not present vascular tissue and do not generate an embryo. However, both types of organisms share the possession of photosynthetic pigments, which absorb and release energy that is later used by the cell. These pigments in addition to chlorophylls, are phycobiliproteins, fucoxanthins, xanthophylls and carotenes, which serve to trap the energy of li…
Pigments in animals
Pigmentation is used by many animals for protection, by means of camouflage, mimicry, or warning coloration. Some animals including fish, amphibians and cephalopods use pigmented chromatophores to provide camouflage that varies to match the background.
Pigmentation is used in signalling between animals, such as in courtship and reproductive behavior. For example, some cephalopods use their chromatophores to communicate.
Uses
Pigments may be extracted and used as dyes.
Pigments (such as astaxanthin and lycopene) are used as dietary supplements.
