Carolina blue (occasionally referred to as Tar Heel blue or Dialectic blue) is the shade of blue used as one of the official school colors of the University of North Carolina.
The name is derived from the popular usage of "Carolina" to refer to the university. For clarity in branding and marketing, UNC Creative has defined the color as Pantone 542 and declared that the CMYK representation is Cyan 60%, Magenta 19%, Yellow 1%, and Black 4%. This CMYK results in a Hex code of #62C6F2 . However, the university has chosen the hex value of #4B9CD3 as their web safe Carolina Blue due to contrast issues and Section 508 web requirements. [1] None of the colors match the selected Pantone 542 which would be a hex value of #6699C2 , RGB of (102,153,194), and a CMYK value of 47,21,0,24.
The North Carolina Tar Heels athletics department has their own formulation for Carolina blue. Carolina athletics blue has the same CMYK color representation as the university's version of Carolina blue, but the RGB representation for Carolina athletics blue is Red 123, Green 175, and Blue 212. This results in a Hex code of #7BAFD4 , the official matching hex code for Pantone 542 C. [2] [3]
Use of the light blue color at UNC dates from 1795 when the Dialectic (blue) and Philanthropic (white) Societies of the university chose representative colors. Society members would wear a blue or white ribbon at university functions, and blue or white ribbons were attached to the diplomas of graduates. [4] Light blue and white have been UNC's sporting colors since the 1880s, when UNC's football team adopted the light blue and white of the Di-Phi Societies as their colors. [5]
The CMYK color model 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).
Pantone LLC is an American limited liability company headquartered in Carlstadt, New Jersey, and best known for its Pantone Matching System (PMS), a proprietary color space used in a variety of industries, notably graphic design, fashion design, product design, printing, and manufacturing and supporting the management of color from design to production, in physical and digital formats, among coated and uncoated materials, cotton, polyester, nylon and plastics.
The Natural Colour System (NCS) is a proprietary perceptual color model. It is based on the color opponency hypothesis of color vision, first proposed by German physiologist Ewald Hering. The current version of the NCS was developed by the Swedish Colour Centre Foundation, from 1964 onwards. The research team consisted of Anders Hård, Lars Sivik and Gunnar Tonnquist, who in 1997 received the AIC Judd award for their work. The system is based entirely on the phenomenology of human perception and not on color mixing. It is illustrated by a color atlas, marketed by NCS Colour AB in Stockholm.
Web colors are colors used in 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 triplet, in hexadecimal format 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.
The CIELAB color space, also referred to as L*a*b*, is a color space defined by the International Commission on Illumination in 1976. It expresses color as three values: L* for perceptual lightness and a* and b* for the four unique colors of human vision: red, green, blue and yellow. CIELAB was intended as a perceptually uniform space, where a given numerical change corresponds to a similar perceived change in color. While the LAB space is not truly perceptually uniform, it nevertheless is useful in industry for detecting small differences in color.
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 Dialectic and Philanthropic Societies, Inc. commonly known as DiPhi or The Societies, are the original collegiate debating societies at the University of North Carolina at Chapel Hill, and together comprise the oldest student organization at the University, as well as the oldest public student organization in the United States. During the academic year, the Societies hold regular meetings at 7:30 PM on Mondays in the Dialectic Chamber at the top of the New West Building. The Societies also hold occasional social events in the Philanthropic Chamber at the top of New East Building.
Palatinate or palatinate purple is a purple colour associated with Durham University and the County and City of Durham. The term has been used to refer to a number of different shades of purple. The Oxford English Dictionary defines it as a "light purple or lavender colour", which is used for Durham academic hoods. For corporate purposes Durham University uses a darker shade.
In optics, orange has a wavelength between approximately 585 and 620 nm and a hue of 30° in HSV color space. In the RGB color space it is a secondary color numerically halfway between gamma-compressed red and yellow, as can be seen in the RGB color wheel. The complementary color of orange is azure. Orange pigments are largely in the ochre or cadmium families, and absorb mostly blue light.
Cambridge Blue is the colour commonly used by sports teams from the University of Cambridge. There is contextual and historical variation. The colour used since the mid-20th century by Cambridge University Boat Club is greener than that used by Cambridge University R.U.F.C.. This rowing colour was created when Alf Twinn, the boatman from 1934 to 1984, added more yellow to this shade, reportedly to distinguish it from the rugby club's colour.
Varieties of the color green may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
Varieties of the color red may differ in hue, chroma or 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.
The color magenta has notable tints and shades. These various colors are shown below.
A color space is a specific organization of colors. In combination with color profiling supported by various physical devices, it supports reproducible representations of color – whether such representation entails an analog or a digital representation. A color space may be arbitrary, i.e. with physically realized colors assigned to a set of physical color swatches with corresponding assigned color names, or structured with mathematical rigor. A "color space" is a useful conceptual tool for understanding the color capabilities of a particular device or digital file. When trying to reproduce color on another device, color spaces can show whether shadow/highlight detail and color saturation can be retained, and by how much either will be compromised.
Varieties of the color yellow may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a yellow or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
