Martin–Schultz Scale
The Martin–Schultz scale is a standard color scale commonly used in physical anthropology to establish more or less precisely the eye color of an individual; it was created by the anthropologists Rudolf Martin and Bruno K Schultz in the first half of the 20th century. The scale consists of 20 colors (from light blue to dark brown-black) that correspond to the different eye colors observed in nature due to the amount of melanin in the iris (in this case, the lower the number, the lighter the eye color): *1-2: blue iris (1a, 1b, 1c, 2a : light blue iris - 2b: darker blue iris) *3: blue-gray iris *4: gray iris (4a, 4b) *5: blue-gray iris with yellow/brown spots *6: gray-green iris with yellow/brown spots *7: green iris *8: green iris with yellow/brown spots *9-10-11: light-brown and hazel iris *12-13: medium brown iris *14-15-16: dark-brown and black iris See also *Eye color * Martin scale *Human eye The human eye is a sensory organ, part of the sensory nervous system, tha ...

Physical Anthropology
Biological anthropology, also known as physical anthropology, is a scientific discipline concerned with the biological and behavioral aspects of human beings, their extinct hominin ancestors, and related non-human primates, particularly from an evolutionary perspective. This subfield of anthropology systematically studies human beings from a biological perspective. Branches As a subfield of anthropology, biological anthropology itself is further divided into several branches. All branches are united in their common orientation and/or application of evolutionary theory to understanding human biology and behavior. * Bioarchaeology is the study of past human cultures through examination of human remains recovered in an archaeological context. The examined human remains usually are limited to bones but may include preserved soft tissue. Researchers in bioarchaeology combine the skill sets of human osteology, paleopathology, and archaeology, and often consider the cultural and m ...

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 ...

Rudolf Martin (anthropologist)
Rudolf Martin (1 July 1864 – 11 July 1925) was a Swiss anthropologist, specializing in physical anthropology. Martin's second wife, Stefanie Oppenheim, survived him and edited a second (1928) edition of his physical anthropology textbook. Rudolf Martin’s Historical Archive Rudolf Martin was a Professor of Physical Anthropology in Munich, who had become inspired by the discovery of the ‘Java Man’ (Pithecanthropus erectus) in 1893 in Java, by the Dutch anthropologist Eugene Dubois. Dubois' publications on the 'Missing Link' became the CenterPoint of the Archive of Rudolf Martin, comprising more than 43,000 historical documents, manuscripts, scientific books and journals. The Archive been safeguarded in 1940 from Germany just before WW II. It went to the Institute of Physical Anthropology of Utrecht University until the institute was discontinued in 1993. After rescuing it from destruction, Slikkerveer became the owner of the oldest palaeo-anthropological archive in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Martin Scale
The Martin scale is an older version of color scale commonly used in physical anthropology to establish more or less precisely the eye color of an individual. It was created by the anthropologist Rudolf Martin in the first half of the 20th century. Later he improved this scale with cooperation of Bruno K. Schultz, leading to the Martin-Schultz scale. Original scale The original Martin scale, summarized below, consists of 16 colors (from light blue to dark brown-black) that correspond to the different eye colors observed in nature due to the amount of melanin in the iris. The numbering is reversed in order to match the Martin–Schultz scale, which is still used in biological anthropology. In this case, the higher the number, the lighter the eye color. Light and light-mixed eyes (16-9) * 16: light-blue iris * 15-14-13: blue iris * 12-11: light-gray iris * 10-9: dark-gray iris Mixed eyes (8-7) * 8: green iris * 7: green-brown iris Dark-mixed eyes (6-5) * 6: hazel iri ...

Human Eye
The human eye is a sensory organ, part of the sensory nervous system, that reacts to visible light and allows humans to use visual information for various purposes including seeing things, keeping balance, and maintaining circadian rhythm. The eye can be considered as a living optical device. It is approximately spherical in shape, with its outer layers, such as the outermost, white part of the eye (the sclera) and one of its inner layers (the pigmented choroid) keeping the eye essentially light tight except on the eye's optic axis. In order, along the optic axis, the optical components consist of a first lens (the cornea—the clear part of the eye) that accomplishes most of the focussing of light from the outside world; then an aperture (the pupil) in a diaphragm (the iris—the coloured part of the eye) that controls the amount of light entering the interior of the eye; then another lens (the crystalline lens) that accomplishes the remaining focussing of light i ...

Color Scales
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electromagn ...
