Brown
Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing or painting, brown is usually made by combining the colors orange and black. In the RGB color model used to project colors onto television screens and computer monitors, brown combines red and green. The color brown is seen widely in nature, wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; it is often associated with plainness, the rustic, feces, and poverty.

Brown Hair
Brown hair, also referred to as brunet (male) or brunette (female), is the second most common human hair color, after black hair. It varies from light brown to a medium dark hair. It is characterized by higher levels of the dark pigment eumelanin and lower levels of the pale pigment pheomelanin. Brown hair is common among populations in the Western world, especially among those from Northwestern Europe, Central Europe, Southeastern Europe, Eastern Europe, Southern Europe, Southern Cone,Brazil, Colombia, Costa Rica, Puerto Rico and the United States, and also some populations in the Middle East where it transitions smoothly into black hair.Frost, Peter"Why Do Europeans Have So Many Hair and Eye Colors?"(summarizing Frost, P. 2006.

Eye Color
Eye color is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. The appearance of blue, green, and hazel eyes results from the Tyndall scattering of light in the stroma, a phenomenon similar to that which accounts for the blueness of the sky called Rayleigh scattering. Neither blue nor green pigments are ever present in the human iris or ocular fluid. Eye color is thus an instance of structural color and varies depending on the lighting conditions, especially for lighter-colored eyes. The brightly colored eyes of many bird ...

Umber
Umber is a natural brown earth pigment that contains iron oxide and manganese oxide. In its natural form, it is called raw umber. When Calcination, calcined, the color becomes warmer and it becomes known as burnt umber. Its name derives from ''terra d'ombra'', or earth of Umbria, the Italian name of the pigment. Umbria is a mountainous region in central Italy where the pigment was originally extracted. The word also may be related to the Latin word ''umbra'', meaning "shadow". Umber is not one precise color, but a range of different colors, from medium to dark in value, from greenish to reddish in hue. The color of the natural earth depends primarily upon the proportions of iron oxide and manganese in the clay. Umber earth pigments contain between five and twenty percent manganese oxide, which accounts for their being a darker and less saturated color than the related earth pigment, sienna. Commercial umber pigments vary in color depending on their origin and how they are proces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
