No long ago posted a post about the color of horses, a nice original issue that if we had on mind to mention it comprehensive it would take a lot of posts to write about. <\/span><\/span>
\nhttp:\/\/xromata.com\/?p=2097 <\/span>
\nWell, you who do not know, did you ever wondered how is "painted" the colorful animal kingdom? Where from gets its “paints” and how they are spread over the vast number of its species? <\/span>
\nAre there any rules about the coloring of all these different genres? <\/span>
\nMaybe there is hiding some "mystery" behind the color palette of nature? <\/span>
\nThe reference to the colors of the horses were as input for the color pigments of the animal kingdom, so to understand that there is a "class" and "law" in "painting" animals and plants. <\/span>
\nBefore we begin the references to the coloring of the animal and plant kingdoms and in general the living world, we must refer briefly to the “dyes”, the so-called organic pigments, which give wonderful colors and color combinations to the innumerable members of the living world. In biology, pigment is any colored cell of animal or plant. <\/span>
\nMany biological structures such as skin, eye iris, hair, contain pigments (such as melanin) in specialized cells called chromophore cells. <\/span>
\nMany conditions affect the level or nature of pigments in animals, plants, in some cells of primaries and fungi.<\/span>
\n<\/span>E.g. albinism and vitiligo are disorders that affect the level of melanin production in animals. <\/span><\/span><\/span>
\nThe color due to pigments differs from the structural color produced by reflections due to the manufacturing of cell structure. <\/span>
\nThe colors caused by pigments appear stable from all viewing angles, something that do not happen on the colors derived as the result of selective reflection or iridescence due of the multilayered structure of cells. <\/span>
\nAbout biological pigments, coloring of the animal and flora world will talk again soon. <\/span>
