  2. CMYK color model - Wikipedia

    en.wikipedia.org/wiki/CMYK_color_model

    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: c yan, m agenta, y ellow, and k ey (black).

    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.

  5. Complementary colors - Wikipedia

    en.wikipedia.org/wiki/Complementary_colors

    In the RGB model, the primary colors are red, green, and blue. The complementary primary–secondary combinations are red – cyan, green – magenta, and blue – yellow. In the RGB color model, the light of two complementary colors, such as red and cyan, combined at full intensity, will make white light, since two complementary colors contain ...

    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: red.

    As of 2011, most graphic cards define pixel values in terms of the colors red, green, and blue. The typical range of intensity values for each color, 0–255, is based on taking a binary number with 32 bits and breaking it up into four bytes of 8 bits each. 8 bits can hold a value from 0 to 255.

  9. Color mixing - Wikipedia

    en.wikipedia.org/wiki/Color_mixing

    For practical additive color models, an equal superposition of all primaries results in neutral (gray or white). In the RGB model, an equal mixture of red and green is yellow, an equal mixture of green and blue is cyan and an equal mixture of blue and red is magenta. [ 1]: 4.2 Yellow, cyan and magenta are the secondary colors of the RGB model.
