  2. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    Every secondary color is the complement of one primary color: cyan complements red, magenta complements green, and yellow complements blue. When all the primary colors are mixed in equal intensities, the result is white. The RGB color model itself does not define what is meant by red, green, and blue colorimetrically, and so the results of ...

  3. Color mixing - Wikipedia

    en.wikipedia.org/wiki/Color_mixing

    For all additive color models, the absence of all primaries results in black. 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.

  4. RYB color model - Wikipedia

    en.wikipedia.org/wiki/RYB_color_model

    RYB (an abbreviation of red–yellow–blue) is a subtractive color model used in art and applied design in which red, yellow, and blue pigments are considered primary colors. [1] Under traditional color theory , this set of primary colors was advocated by Moses Harris , Michel Eugène Chevreul , Johannes Itten and Josef Albers , and applied by ...

  5. Red - Wikipedia

    en.wikipedia.org/wiki/Red

    In the RGB color model, red, green and blue are additive primary colors. Red, green and blue light combined makes white light, and these three colors, combined in different mixtures, can produce nearly any other color. This principle is used to generate colors on such as computer monitors and televisions.

  6. Complementary colors - Wikipedia

    en.wikipedia.org/wiki/Complementary_colors

    The RGB color model, invented in the 19th century and fully developed in the 20th century, uses combinations of red, green, and blue light against a black background to make the colors seen on a computer monitor or television screen. In the RGB model, the primary colors are red, green, and blue.

    But that same phenomenon can also sometimes make skies look red or orange. Here's a breakdown of how and why it all happens. But the science behind a blue sky isn't that easy.

  8. 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:
