  2. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    The RGB color model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

  3. Shades of red - Wikipedia

    en.wikipedia.org/wiki/Shades_of_red

    Red (RGB), RGB red, or electric red [citation needed] (as opposed to pigment red, shown below) is the brightest possible red that can be reproduced on a computer monitor. This color is an approximation of an orangish red spectral color. It is one of the three primary colors of light in the RGB color model, along with green and blue.

  4. Red - Wikipedia

    en.wikipedia.org/wiki/Red

    It is a primary color in the RGB color model and the light just past this range is called infrared, or below red, and cannot be seen by human eyes, although it can be sensed as heat. In the language of optics, red is the color evoked by light that stimulates neither the S or the M (short and medium wavelength) cone cells of the retina, combined ...

  5. Web colors - Wikipedia

    en.wikipedia.org/wiki/Web_colors

    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.

  6. RGB color spaces - Wikipedia

    en.wikipedia.org/wiki/RGB_color_spaces

    1931 CIE chromaticity diagram showing some RGB color spaces as defined by their chromaticity triangles. RGB color spaces are additive colorimetric color spaces specifying part of its absolute color space definition using the RGB color model.

    The rg chromaticity space is used in computer vision applications, and shows the color of light (red, yellow, green, etc.), but not its intensity (dark, bright). LMS color space (long, medium, short), a perceptual color space based on the response functions of the cones in the retina of the eye.

  8. 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.

  9. sRGB - Wikipedia

    en.wikipedia.org/wiki/SRGB

    sRGB is a standard RGB (red, green, blue) color space that HP and Microsoft created cooperatively in 1996 to use on monitors, printers, and the World Wide Web. It was subsequently standardized by the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999.

  10. RGBA color model - Wikipedia

    en.wikipedia.org/wiki/RGBA_color_model

    RGBA stands for red green blue alpha. While it is sometimes described as a color space, it is actually a three-channel RGB color model supplemented with a fourth alpha channel.

  11. Wide-gamut RGB color space - Wikipedia

    en.wikipedia.org/wiki/Wide-gamut_RGB_color_space

    The wide-gamut RGB color space (or Adobe Wide Gamut RGB) is an RGB color space developed by Adobe Systems, that offers a large gamut by using pure spectral primary colors. It is able to store a wider range of color values than sRGB or Adobe RGB color spaces.
