What Colors Do Red and Yellow Make

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, (which some artists see as the "correct theory" whilst others use modern color theory [cym] instead) this set of primary colors was advocated by Moses Harris, Michel Eugène Chevreul, Johannes Itten and Josef Albers, and applied by countless artists and designers. The RYB color model underpinned the color curriculum of the Bauhaus, Ulm School of Design and numerous art and design schools that were influenced by the Bauhaus, including the IIT Institute of Design (founded as the New Bauhaus), Black Mountain College, Design Department Yale University, the Shillito Design School, Sydney, and Parsons School of Design, New York.

In this context, the term primary color refers to three exemplar colors (red, yellow, and blue) as opposed to specific pigments. As illustrated, in the RYB color model, red, yellow, and blue are intermixed to create secondary color segments of orange, green, and purple. This set of primary colors emerged at a time when access to a large range of pigments was limited by availability and cost, and it encouraged artists and designers to explore the many nuances of color through mixing and intermixing a limited range of pigment colors. In art and design education, red, yellow, and blue pigments were usually augmented with white and black pigments, enabling the creation of a larger gamut of color nuances including tints and shades.

The RYB color model relates specifically to color in the form of paint and pigment application in art and design.[2] Other common color models include the light model (RGB) and the printing ink CMY color model, the latter emerging in conjunction with the CMYK color model in the printing industry.

History [edit]

The 1613 RYB color scheme of Franciscus Aguilonius (Francisci Agvilonii), with primaries yellow (flavus), red (rubeus), and blue (caeruleus) arranged between white (albus) and black (niger), with orange (aureus), green (viridis), and purple (purpureus) as combinations of two primaries.

Le Blon's 1725 description of mixing red, yellow, and blue paints or printing inks

The first scholars to propose that there are three primary colors for painters were Scarmiglioni (1601), Savot (1609), de Boodt (1609) and Aguilonius (1613).[3] From these, the most influential was the work of Franciscus Aguilonius (1567–1617), although he did not arrange the colors in a wheel.[4]

Jacob Christoph Le Blon was the first to apply the RYB color model to printing, specifically mezzotint printing, and he used separate plates for each color: yellow, red and blue plus black to add shades and contrast. In 'Coloritto', Le Blon asserted that "the art of mixing colours…(in) painting can represent all visible objects with three colours: yellow, red and blue; for all colours can be composed of these three, which I call Primitive". Le Blon added that red and yellow make orange; red and blue, make purple; and blue and yellow make green (Le Blon, 1725, p6).[5] [6]

In the 18th century, Moses Harris advocated that a multitude of colors can be created from three "primitive" colors – red, yellow, and blue.[7]

Mérimée referred to "three simple colours (yellow, red, and blue)" that can produce a large gamut of color nuances. "United in pairs, these three primitive colours give birth to three other colours as distinct and brilliant as their originals; thus, yellow mixed with red, gives orange; red and blue, violet; and green is obtained by mixing blue and yellow" (Mérimée, 1839, p245). Mérimée illustrated these color relationships with a simple diagram located between pages 244 and 245: Chromatic Scale (Echelle Chromatique).De la peinture à l'huile : ou, Des procédés matériels employés dans ce genre de peinture, depuis Hubert et Jean Van-Eyck jusqu'à nos jours was published in 1830 and an English translation by W. B. Sarsfield Taylor was published in London in 1839.[8]

Similar ideas about the creation of color using red, yellow, and blue were discussed in Theory of Colours (1810) by the German poet, color theorist and government minister Johann Wolfgang von Goethe.[9]

In The Law of Simultaneous Color Contrast (1839) by the French industrial chemist Michel Eugène Chevreul discussed the creation of numerous color nuances and his color theories were underpinned by the RYB color model.[10]

Separate to the RYB color model, cyan, magenta, and yellow primary colors are associated with CMYK commonly used in the printing industry. Cyan, magenta, and yellow are often referred to as "process blue", "process red", and "process yellow".[11] [12]
