  2. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    Hexadecimal 8-bit RGB representations of the main 125 colors. A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet ( r, g, b ), each component of which can vary from zero to a defined maximum value.

  3. Secondary color - Wikipedia

    en.wikipedia.org/wiki/Secondary_color

    A RYB color wheel with tertiary colors described under the modern definition. RYB is a subtractive mixing color model, used to estimate the mixing of pigments (e.g. paint) in traditional color theory, with primary colors red, yellow, and blue. The secondary colors are green, purple, and orange as demonstrated here:

  4. Complementary colors - Wikipedia

    en.wikipedia.org/wiki/Complementary_colors

    In the traditional RYB color model, the complementary color pairs are red – green, yellow – purple, and blue – orange. Opponent process theory suggests that the most contrasting color pairs are red–green and blue–yellow. The black - white color pair is common to all the above theories.

  5. Shades of violet - Wikipedia

    en.wikipedia.org/wiki/Shades_of_violet

    Dark reddish purple. B: Normalized to [0–255] (byte) The color Japanese violet or Sumire is shown at right. This is the color called "violet" in the traditional Japanese colors group, a group of colors in use since beginning in 660 CE in the form of various dyes that are used in designing kimono.

  6. Violet (color) - Wikipedia

    en.wikipedia.org/wiki/Violet_(color)

    Violet light has a wavelength between approximately 380 and 435 nanometers. [2] The color's name is derived from the Viola genus of flowers. [3] [4] 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.

  7. Color wheel - Wikipedia

    en.wikipedia.org/wiki/Color_wheel

    In a paint or subtractive color wheel, the "center of gravity" is usually (but not always) black, representing all colors of light being absorbed. Additive. A color wheel based on RGB (red, green, blue) additive primaries has cyan, magenta, and yellow secondaries. Alternatively, the same arrangement of colors around a circle can be described as ...

  8. Web colors - Wikipedia

    en.wikipedia.org/wiki/Web_colors

    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 (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.

  9. Purple - Wikipedia

    en.wikipedia.org/wiki/Purple

    In the CMYK color model used in modern printing, purple is made by combining magenta pigment with either cyan pigment, black pigment, or both. In the RGB color model used in computer and television screens, purple is created by mixing red and blue light in order to create colors that appear similar to violet light.

  10. Color mixing - Wikipedia

    en.wikipedia.org/wiki/Color_mixing

    Color mixing. Additive color mixing can be illustrated with colored lights. There are three types of color mixing models, depending on the relative brightness of the resultant mixture: additive, subtractive, and average. [1] In these models, mixing black and white will yield white, black and gray, respectively.

  11. List of color spaces and their uses - Wikipedia

    en.wikipedia.org/wiki/List_of_color_spaces_and...

    RGB (red, green, blue) describes the chromaticity component of a given color, when excluding luminance. RGB itself is not a color space, it is a color model. There are many different color spaces that employ this color model to describe their chromaticities because the R/G/B chromaticities are one facet for reproducing color in CRT & LED displays.
