Tertiary Colors
A tertiary color or intermediate color is a color made by mixing full saturation of one primary color with half saturation of another primary color and none of a third primary color, in a given color space such as RGB, CMYK (more modern) or RYB (traditional). Tertiary colors have general names, one set of names for the RGB color wheel and a different set for the RYB color wheel. These names are shown below. Another definition of tertiary color is provided by color theorists such as Moses Harris and Josef Albers, who suggest that tertiary colors are created by intermixing pairs of secondary colors: orange-green, green-purple, purple-orange; or by intermixing complementary colors. This approach to tertiary color relates specifically to color in the form of paints, pigments, and dyes. Comparison of RGB and RYB color wheels The RYB color wheel was invented centuries before the 1890s, when it was found by experiment that magenta, yellow, and cyan are the primary colors of pigment, n ...

Color Diagram Charles Hayter
Color (American English) or colour (British English) is the visual perception, visual perceptual Physical property, 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 psychophysics, psychophysical perception of color appearance. Color science includes the color vision, perception of color by the human eye, eye and brain, the origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CMYK
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'' because inks "subtract" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the "additive" combination of all primary colored lights, black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of colo ...

Amber (color)
The color amber is a pure chroma color, located on the color wheel midway between the colors of yellow and orange. The color name is derived from the material also known as amber, which is commonly found in a range of yellow-orange-brown-red colors; likewise, as a color ''amber'' can refer to a range of yellow-orange colors. In English, the first recorded use of the term as a color name, rather than a reference to the specific substance, was in 1500. SAE/ECE amber Amber is one of several technically defined colors used in automotive signal lamps. In North America, SAE standard J578 governs the colorimetry of vehicle lights, while outside North America the internationalized European ECE regulations hold force. Both standards designate a range of orange-yellow hues in the CIE color space as "amber". In the past, the ECE amber definition was more restrictive than the SAE definition, but the current ECE definition is identical to the more permissive SAE standard. The SAE for ...

Vermilion
Vermilion (sometimes vermillion) is a color, color family, and pigment most often made, since ancient history, antiquity until the 19th century, from the powdered mineral cinnabar (a form of mercury sulfide, which is toxic) and its corresponding color. It is very often synonymous with red orange, which often takes a modern form just 11% brighter (at full brightness). Etymology and orthography The word vermilion came from the Old French language, Old French word ''vermeillon'', which was derived from ''vermeil'', from the Latin ''vermiculus'', the diminutive of the Latin word ''vermis'', or worm. The name originated because it had a similar color to the natural red dye made from an insect, ''Kermes vermilio'', which was widely used in Europe. The first recorded use of "vermilion" as a color name in English language, English was in 1289. The term cinnabar was used interchangeably with vermilion until the 17th century, when vermilion became the more common name. Now the term "ci ...

Purple
Purple is any of a variety of colors with hue between red and blue. In the RGB color model used in computer and television screens, purples are produced by mixing red and blue light. In the RYB color model historically used by painters, purples are created with a combination of red and blue pigments. In the CMYK color model used in printing, purples are made by combining magenta pigment with either cyan pigment, black pigment, or both. Purple has long been associated with royalty, originally because Tyrian purple dye, made from the mucus secretion of a species of snail, was extremely expensive in antiquity. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the emperor and aristocracy. According to contemporary surveys in Europe and the United States, purple is the color most ofte ...

Azure (color)
Azure ( , ) is the color between cyan and blue on the spectrum of visible light. It is often described as the color of the sky on a clear day. On the RGB color wheel, "azure" ( hexadecimal #0080FF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a 50% of green light to a 100% of blue light. In the X11 color system, which became a model for early web colors, azure is depicted as a pale cyan or white cyan. Etymology and history The color azure ultimately takes its name from the intense blue mineral lapis lazuli. ' is the Latin word for "stone" and ' is the genitive form of the Medieval Latin ', which is taken from the Arabic ''lāzaward'', itself from the Persian ''lāžaward'', which is the name of the stone in Persian and also of a place where lapis lazuli was mined.

Spring Green
Spring green is a color that was traditionally considered to be on the yellow side of green, but in modern computer systems based on the RGB color model is halfway between cyan and green on the color wheel. The modern spring green, when plotted on the CIE chromaticity diagram, corresponds to a visual stimulus of about 505 nanometers on the visible spectrum. In HSV color space, the expression of which is known as the RGB color wheel, ''spring green'' has a hue of 150°. Spring green is one of the tertiary colors on the RGB color wheel, where it is the complementary color of rose. The first recorded use of ''spring green'' as a color name in English was in 1766, referring to roughly the color we now call ''spring bud''. Spring green (computer) Spring green (HTML) ''Spring green'' is a web color, common to X11 and HTML. Medium spring green Displayed at right is the color medium spring green. ''Medium spring green'' is a web color. It is close to but not right on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange (color)
Orange is the colour between yellow and red on the spectrum of visible light. Human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red. In the RGB colour model, it is a tertiary colour. It is named after the fruit of the same name. The orange colour of many fruits and vegetables, such as carrots, pumpkins, sweet potatoes, and oranges, comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the Sun into chemical energy for the plants' growth. Similarly, the hues of autumn leaves are from the same pigment after chlorophyll is removed. In Europe and America, surveys show that orange is the colour most associated with amusement, the unconventional, extroversion, warmth, fire, energy, activity, danger, taste and aroma, the autumn and Allhallowtide s ...

Rose (color)
Rose is the color halfway between red and magenta on the HSV color wheel, also known as the RGB color wheel, on which it is at hue angle of 330 degrees. Rose is one of the tertiary colors on the HSV (RGB) color wheel. The complementary color of rose is spring green. Sometimes rose is quoted instead as the web-safe color FF00CC, which is closer to magenta than to red, corresponding to a hue angle near 320 degrees, or the web-safe color FF0077, which is closer to red than magenta, corresponding to a hue angle of about 340 degrees. Shades of rose Etymology of rose The first recorded use of ''rose'' as a color name in English was in 1382.Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 203 The etymology of the color name rose is the same as that of the name of the rose flower. The name originates from Latin ''rosa'', borrowed through Oscan from colonial Greek in southern Italy: ''rhodon'' (Aeolic form: ''wrodon''), from Aramaic ''wurrdā'', from Ass ...

Violet (color)
Violet is the color of light at the short wavelength end of the visible spectrum, between blue and invisible ultraviolet. It is one of the seven colors that Isaac Newton labeled when dividing the spectrum of visible light in 1672. Violet light has a wavelength between approximately 380 and 435 nanometers. The color's name is derived from the violet flower. In the RGB color model used in computer and television screens, violet is produced by mixing red and blue light, with more blue than red. In the RYB color model historically used by painters, violet is created with a combination of red and blue pigments and is located between blue and purple on the color wheel. In the CMYK color model used in printing, violet is created with a combination of magenta and cyan pigments, with more magenta than cyan. Violet is closely associated with purple. In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of ...
