    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/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 ...

    en.wikipedia.org/wiki/RGB_color_model

    A diagram demonstrating additive color with RGB. The RGB color model is an additive color model [1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors.

    en.wikipedia.org/wiki/Additive_color

    Additive color or additive mixing is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. [1] Modern formulations of Grassmann's laws [2] describe the additivity in the color perception of ...

  6. Color theory - Wikipedia

    en.wikipedia.org/wiki/Color_theory

    Color theory asserts three pure primary colors that can be used to mix all possible colors. These are sometimes considered as red, yellow and blue or as red, green and blue . [citation needed] Ostensibly, any failure of specific paints or inks to match this ideal performance is due to the impurity or imperfection of the colorants.

  7. Purple - Wikipedia

    en.wikipedia.org/wiki/Purple

    Purple is a color similar in appearance to violet light. In the RYB color model historically used in the arts, purple is a secondary color created by combining red and blue pigments. In the CMYK color model used in modern printing, purple is made by combining magenta pigment with either cyan pigment, black pigment, or both.

  8. Violet (color) - Wikipedia

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

    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. In the RYB color model historically used by painters, violet is created with a combination of red and blue pigments and is located between blue and purple on the color wheel.
