  • Interesting fact: The reason why hair turns gray as we age is because the pigment cells in the hair follicle start to die, which is responsible for producing "melanin" which gives the hair colour
    • Pigment Any material from which a dye, a paint, or the like, may be prepared; particularly, the refined and purified coloring matter ready for mixing with an appropriate vehicle.

  • Interesting fact: The reason why flamingos are pink is because they eat shrimp which have a red pigment
    • n pigment Any substance that is or can be used by painters to impart color to bodies; technically, a dry substance, usually in the form of a powder or in lumps so lightly held together as to be easily pulverized, which after it has been mixed with a liquid medium can be applied by painters to surfaces to be colored. Pigment is properly restricted to the dry coloring matter which when mixed with a vehicle becomes a. paint; but the two words are commonly used without discrimination. (See paint.) In oil-painting, the pigments are ground or triturated to render them smooth, usually in poppy- or nut-oil, since these dry best and do not deaden the colors.
    • n pigment In biology, organic coloring matter; any organized substance whose presence in the tissues of animals and plants colors them. Pigment is the generic or indifferent term, most kinds of pigment having specific names. Coloring matter of one kind or another is almost universal in animals and plants, comparatively few of which are colorless. Pigments are very generally distributed in the integument and its appendages, as the skin, and especially the fur, feathers, scales, etc., of animals, and the leaves and other soft parts of plants. The dark color of the negro's skin is due to the abundance of pigment in the epidermis. The black appearance of the pupil of the eye is due to the heavy pigmentation of the choroid, and various colors of the iris depend upon specific pigments. Such coloring matters are often collected in special sacs which open and shut, producing the “shot” or play of color of the chameleon, dolphin, cuttlefish, and other animals. In many low animals and plants the color of the pigment is characteristic of genera, families, or even higher groups, as among infusorians, algals, etc. See cut under cell.

Should be a bit of heaven;
My brush, a sunbeam; pigments, dawn
And night and starry even.

Of azaleas, yet burnt out
Quick as they. To follow the light's tint
And intensity by midnight
By noon and throughout the brunt

Holding not on his palette the tint of a kiss,
Nor a pigment to hint of the hue of her hair
Nor the gold of her smile-- O what artist could dare
To expect a result half so fair?
"A Discouraging Model" by James Whitcomb Riley

In science:

The quantum phase factors allow us to consider the space structure of the pigments.
Complex quantum network model of energy transfer in photosynthetic complexes
There exist some optimal phase regions where the transfer efficiency takes its maxima, which indicates that when the pigments are optimally spaced, the exciton can pass through the FMO with perfect efficiency.
Complex quantum network model of energy transfer in photosynthetic complexes
However, all these models cannot describe the space distribution of the pigments.
Complex quantum network model of energy transfer in photosynthetic complexes
As we know, the space distribution of the pigments is very important for exciton energy transfer and the experimental evidence also shows that the optimized space distribution of the pigments is one factor for prefect energy transfer in light-harvesting complexes [2, 3].
Complex quantum network model of energy transfer in photosynthetic complexes
Therefore, it is necessary to set up a quantum model in which the space distribution of the pigments is considered.
