Seal brown is a rich dark brown color, resembling the color of the dyed fur from the fur seal.
The specifications for the U.S. Army Air Corps Type A-2 jacket (regulation summer flying jacket), adopted in 1931 and the most familiar among all leather flight jackets, stated that it should be made of horsehide tanned to seal brown.[ citation needed ] However, initially, oxidation during the dyeing process caused the jackets to end up russet (a lighter, reddish brown) in color.[ citation needed ] Later in the decade, they were able to prevent oxidation during dyeing, and the jackets produced were a proper dark brown.[ citation needed ]
Seal brown is one of the official colors of Lehigh University, Brown University, [2] the Cleveland Browns football team, [3] and the engineering honor society, Tau Beta Pi. [4]
Black is a color that results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and grey. It is often used symbolically or figuratively to represent darkness. Black and white have often been used to describe opposites such as good and evil, the Dark Ages versus Age of Enlightenment, and night versus day. Since the Middle Ages, black has been the symbolic color of solemnity and authority, and for this reason it is still commonly worn by judges and magistrates.
Sienna is an earth pigment containing iron oxide and manganese oxide. In its natural state, it is yellowish brown, and it is called raw sienna. When heated, it becomes a reddish brown, and it is called burnt sienna. It takes its name from the city-state of Siena, where it was produced during the Renaissance. Along with ochre and umber, it was one of the first pigments to be used by humans, and is found in many cave paintings. Since the Renaissance, it has been one of the brown pigments most widely used by artists.
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 and painting, brown is usually made by combining the colors orange and black.
Magenta is a purplish-red color. On color wheels of the RGB (additive) and CMY (subtractive) color models, it is located precisely midway between blue and red. It is one of the four colors of ink used in color printing by an inkjet printer, along with yellow, cyan, and black to make all the other colors. The tone of magenta used in printing, printer's magenta, is redder than the magenta of the RGB (additive) model, the former being closer to rose.
A pigment is a powder used to add color or change visual appearance. Pigments are completely or nearly insoluble and chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use. Dyes are often organic compounds whereas pigments are often inorganic. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli.
Crimson is a rich, deep red color, inclining to purple. It originally meant the color of the kermes dye produced from a scale insect, Kermes vermilio, but the name is now sometimes also used as a generic term for slightly bluish-red colors that are between red and rose. It is the national color of Nepal.
Gold, also called golden, is a color tone resembling the gold chemical element.
Theta Tau (ΘΤ) is a professional collegiate engineering fraternity. The fraternity has programs to promote the social, academic, and professional development of its members. Theta Tau is the oldest and largest professional engineering fraternity and has a membership of more than 50,000 men and women who study engineering in all its various branches on over 100 college campuses.
Hair coloring, or hair dyeing, is the practice of changing the color of the hair on humans' heads. The main reasons for this are cosmetic: to cover gray or white hair, to alter hair to create a specific look, to change a color to suit preference or to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching.
Color theory, or more specifically traditional color theory, is the historical body of knowledge describing the behavior of colors, namely in color mixing, color contrast effects, color harmony, color schemes and color symbolism. Modern color theory is generally referred to as Color science. While there is no clear distinction in scope, traditional color theory tends to be more subjective and have artistic applications, while color science tends to be more objective and have functional applications, such as in chemistry, astronomy or color reproduction. Color theory dates back at least as far as Aristotle's treatise On Colors. A formalization of "color theory" began in the 18th century, initially within a partisan controversy over Isaac Newton's theory of color and the nature of primary colors. By the end of the 19th century, a schism had formed between traditional color theory and color science.
The Tau Beta Pi Association is the oldest engineering honor society and the second oldest collegiate honor society in the United States. It honors engineering students in American universities who have shown a history of academic achievement as well as a commitment to personal and professional integrity. Specifically, the association was founded "to mark in a fitting manner those who have conferred honor upon their Alma Mater by distinguished scholarship and exemplary character as students in engineering, or by their attainments as alumni in the field of engineering, and to foster a spirit of liberal culture in engineering colleges".
Umber is a natural earth pigment consisting of iron oxide and manganese oxide; it has a brownish color that can vary among shades of yellow, red, and green. Umber is considered one of the oldest pigments known to humans, first seen in Ajanta Caves in 200 BC – 600 AD. Umber's advantages are its highly versatile color, warm tone, and quick drying abilities. While some sources indicate that umber's name comes from its geographic origin in Umbria, other scholars suggest that it derives from the Latin word umbra, which means "shadow". The belief that its name derives from the word for shadow is fitting, as the color helps create shadows. The color is primarily produced in Cyprus. Umber is typically mined from open pits or underground mines and ground into a fine powder that is washed to remove impurities. In the 20th century, the rise of synthetic dyes decreased the demand for natural pigments such as umber.
Black light paint or black light fluorescent paint is luminous paint that glows under a black light. It is based on pigments that respond to light in the ultraviolet segment of the electromagnetic spectrum. The paint may or may not be colorful under ordinary light. Black light paint should not be confused with phosphorescent (glow-in-the-dark) or daylight fluorescent paint.
Zeta Beta Tau (ΖΒΤ) is a Greek-letter social fraternity based in North America. It was founded on December 29, 1898. Originally a Zionist youth society, its purpose changed from the Zionism of the fraternity's early years when, in 1954, the fraternity became non-sectarian and open to non-Jewish members, changing its membership policy to include "All Men of Good Character" regardless of religious or ethnic background, while still being recognized as the first Jewish Fraternity.
Pi Lambda Phi (ΠΛΦ), commonly known as Pi Lam, is a social fraternity with 145 chapters. The fraternity was founded in 1895 at Yale University in New Haven, Connecticut. Pi Lambda Phi is headlined by prestigious chapters at Temple University, the Massachusetts Institute of Technology, and the University of Virginia. Pi Lambda Phi is continuously expanding to schools across the country, such as Ohio State University, University of Cincinnati, Pennsylvania State University, Florida State University and East Carolina University. Recent planned expansions include West Virginia University and the University of Pennsylvania.
Thermochromism is the property of substances to change color due to a change in temperature. A mood ring is an excellent example of this phenomenon, but thermochromism also has more practical uses, such as baby bottles which change to a different color when cool enough to drink, or kettles which change color when water is at or near boiling point. Thermochromism is one of several types of chromism.
Old gold is a dark yellow, which varies from light olive or olive brown to deep or strong yellow, generally on the darker side of this range.
Varieties of the color red may differ in hue, chroma, lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors are shown below.
Iron oxide red is a generic name of a ferric oxide pigment of reddish colors. Multiple shades based on both anhydrous Fe
2O
3 and its hydrates were known to painters since prehistory. The pigments were originally obtained from natural sources, since the 20th century they are mostly synthetic. These substances form one of the most commercially important groups of pigments, and their names sometimes reflect the location of a natural source, later transferred to the synthetic analog. Well-known examples include the Persian Gulf Oxide with 75% Fe
2O
3 and 25% silica, Spanish red with 85% of oxide, Tuscan red.
