Colors of parrots

Parrots thanks to their appearance not one person led into the admiration. Owe it to colors added variety. We can divide their colors on chemical and physical. czarny opal Thanks to dyes (pigments) are created chemically colors. As a result of occurring physical phenomena in structures plumage remaining colors called structural colors are arising.

Chemically created colors we can rank among: melanin and psittacin. Melanin is divided on: eumelanin and pheomelanin. Eumelanin gives colors: black, greyness, bronzes and their combinations and shades. Pheomelanin is red-brown and red colors along with their tones. Parrots only produce eumelanin. It is believed that, ability to produce psittacin caused blocking the pheomelanin production. Psittacin appear only at parrots. We can divide them on yellow and red. That is, psittacin includes all colors from the palette yellow and red, from pale yellow through orange to darkness red and all their combinations. Melanin and psittacin can mix with themselves creating all sorts color combinations.

Structural colors are blue and green color. The process of creating the color blue consists in consuming through eumelanin of long light waves, i.e. the color: green, yellow and red at simultaneous reflecting short waves: blue and purple. It is possible thanks to the right structure of prismatic cells, from which plumage are built. Arising from combination yellow color originating from dye and blue color formed thanks to proper light cleaving in cells of plumage a green color result.

White color we can observe everywhere where no dye appears.
