Shades Of Brown
Shades of brown can be produced by combining red, yellow, and black pigments, or by a combination of orange and black—illustrated in the color box. The RGB color model, that generates all colors on computer and television screens, makes brown by combining red and green light at different intensities. Brown color names are often imprecise, and some shades, such as beige, can refer to lighter rather than darker shades of yellow and red. Such colors are less saturated than colors perceived to be orange. Browns are usually described as light or dark, reddish, yellowish, or gray-brown. There are no standardized names for shades of brown; the same shade may have different names on different color lists, and sometimes one name (such as beige or puce) can refer to several very different colors. The X11 color list of web colors has seventeen different shades of brown, but the complete list of browns is much longer. Brown colors are typically desaturated shades of reds, oranges, an ...

X11 Color Names
In computing, on the X Window System, X11 color names are represented in a simple text file, which maps certain strings to RGB color values. It was traditionally shipped with every X11 installation, hence the name, and is usually located in ''<X11root>''/lib/X11/rgb.txt. The web colors list is descended from it but differs for certain color names. Color names are not standardized by Xlib or the X11 protocol. The list does not show continuity either in selected color values or in color names, and some color triplets have multiple names. Despite this, graphic designers and others got used to them, making it practically impossible to introduce a different list. In earlier releases of X11 (prior to the introduction of Xcms), server implementors were encouraged to modify the RGB values in the reference color database to account for gamma correction. As of X.Org Release 7.4 rgb.txt is no longer included in the roll up release, and the list is built directly into the server. Th ...

RYB Color Model
RYB (an abbreviation of red–yellow–blue) is a subtractive color model used in art and applied design in which red, yellow, and blue pigments are considered primary colors. Under traditional color theory, this set of primary colors was advocated by Moses Harris, Michel Eugène Chevreul, Johannes Itten and Josef Albers, and applied by countless artists and designers. The RYB color model underpinned the color curriculum of the Bauhaus, Ulm School of Design and numerous art and design schools that were influenced by the Bauhaus, including the IIT Institute of Design (founded as the New Bauhaus), Black Mountain College, Design Department Yale University, the Shillito Design School, Sydney, and Parsons School of Design, New York. In this context, the term ''primary color'' refers to three exemplar colors (red, yellow, and blue) as opposed to specific pigments. As illustrated, in the RYB color model, red, yellow, and blue are intermixed to create secondary color segments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Millettia Laurentii
''Millettia'' is a genus of flowering plants in the family Fabaceae. It consists of about 169 species of shrubs, lianas or trees, which are native to tropical and subtropical regions of sub-Saharan Africa, the Indian subcontinent, Indochina, southern China, Malesia, and New Guinea. Typical habitats include tropical rain forest and seasonally-dry lowland and upland forest and forest margins, woodland, thicket, wooded grassland, and secondary vegetation. Description In 1834, in ''Prodromus Florae Peninsulae Indiae Orientalis'' Robert Wight and George Arnott Walker-Arnott describe ''Millettia'' as: Calyx cup-shaped, lobed or slightly toothed. Corolla papilionaceous: vexillum recurved, broad, emarginate, glabrous or silky on the back. Stamens diadelphous (9 and 1), the tenth quite distinct. Legume flat, elliptic or lanceolate, pointed, coriaceous, thick margined, wingless indehiscent, 1-2 seeded: valves closely cohering with each other all round the seeds and between them. Twi ...

Hematite
Hematite (), also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of . It has the same crystal structure as corundum () and ilmenite (). With this it forms a complete solid solution at temperatures above . Hematite occurs naturally in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined as an important ore mineral of iron. It is electrically conductive. Hematite varieties include ''kidney ore'', ''martite'' ( pseudomorphs after magnetite), ''iron rose'' and ''specularite'' ( specular hematite). While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. The term ''kidney ore'' may be broadly used to describe botryoidal, mammillary, or reniform hematite. Maghemite is a polymorph of hematite (γ-) with the ...

Burnt Umber
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 used in the Ajanta Caves from 200 BC to 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. History The earliest documented uses of umber date ...

Vanadinite
Vanadinite is a mineral belonging to the apatite group of Phosphate minerals, phosphates, with the chemical formula lead, Pb5(vanadium, Voxygen, O4)3chlorine, Cl. It is one of the main industrial ores of the metal vanadium and a minor source of lead. A dense, brittle mineral, it is usually found in the form of red hexagonal crystals. It is an uncommon mineral, formed by the oxidation of lead ore deposits such as galena. First discovered in 1801 in Mexico, vanadinite deposits have since been unearthed in South America, Europe, Africa, and North America. Origins Vanadinite is an uncommon mineral, only occurring as the result of chemical alterations to a pre-existing material. It is therefore known as a secondary mineral. It is found in arid climates and forms by Redox, oxidation of primary lead minerals. Vanadinite is especially found in association with the lead sulfide, galena. Other associated minerals include wulfenite, limonite, and barite. It was originally discovered in Me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Web Colors
Web colors are colors used in Web design, displaying web pages on the World Wide Web; they can be described by way of three methods: a color may be specified as an RGB color model, RGB triplet, in hexadecimal format (a ''hex triplet'') or according to its common English name in some cases. A color tool or other graphics software is often used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified. Colors outside the sRGB gamut can be specified in CSS, Cascading Style Sheets by making one or more of the red, green and blue components negative or greater than 100%, so the color space is theoretically an unbounded extrapolation of sRGB similar to scRGB. Specifying a non-sRGB ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Tone
Earth tone is a term used to describe a palette of colors that are similar to natural materials and landscapes. These colors are inspired by the earth's natural hues, including browns, greens, grays, and other warm and muted shades. The term earth tone first became popular in the 1970s during the environmental movement, as people sought to reconnect with nature and embrace more natural and organic lifestyles. People often connect earth tones with warmth, comfort, and steadiness, which is why they are commonly used in interior design, fashion, and graphic design. They are also versatile, making them suitable for a wide range of applications, from rustic and traditional to modern and minimalist. Some of the most common earth tones include white, brown, tan, beige, taupe, khaki, green, olive, moss, and rust. These colors are often used together in a variety of combinations to create a connected and natural-looking palette. In interior design, earth tones can be used to create a ca ...
