  2. 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.

    en.wikipedia.org/wiki/Complementary_colors

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

  4. 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: red.

    ROYGBIV is an acronym for the sequence of hues commonly described as making up a rainbow: red, orange, yellow, green, blue, indigo, and violet. When making an artificial rainbow, glass prism is used, but the colors of "ROY-G-BIV" are inverted to VIB-G-YOR". There are several mnemonics that can be used for remembering this color sequence, such ...

  7. Primary color - Wikipedia

    en.wikipedia.org/wiki/Primary_color

    The most common color mixing models are the additive primary colors (red, green, blue) and the subtractive primary colors (cyan, magenta, yellow). Red, yellow and blue are also commonly taught as primary colours, despite some criticism due to its lack of scientific basis.

  8. Color of chemicals - Wikipedia

    en.wikipedia.org/wiki/Color_of_chemicals

    Predicting the color of a compound can be extremely complicated. Some examples include: Cobalt chloride is pink or blue depending on the state of hydration (blue dry, pink with water) so it is used as a moisture indicator in silica gel. Zinc oxide is white, but at higher temperatures becomes yellow, returning to white as it cools.

    The corresponding secondary colors are green, orange, and violet or purple. The tertiary colors are green-yellow, yellow-orange, orange-red, red-violet/purple, purple/violet-blue and blue-green. Non-digital visual artists typically use red, yellow, and blue primaries (RYB color model) arranged at three equally spaced points around their color ...
