This occurs when there is sufficient transparency in the pigments, allowing light to penetrate into the mixed paint, where the two colors together absorb light except wavelengths in the green range. Alternately, if the pigments are highly opaque, a combination of blue and yellow paint appears more grayish.
[10] Out of the opposition of blue and yellow, through a process called "steigerung", or "augmentation" a third color, red, was born. [page needed] Goethe also proposed several sets of complementary colors which "demanded" each other. According to Goethe, "yellow 'demands' violet; orange [demands] blue; purple [demands] green; and vice versa". [11]
In painting and traditional colour theory, blue is one of the three primary colours of pigments (red, yellow, blue), which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Mixing all three primary colours together produces a dark brown.
Primary colors of the CMY color model: cyan, magenta, and yellow, mixed to form secondary colors red, green, and blue. The RGB color model is an additive mixing model, used to estimate the mixing of colored light, with primary colors red, green, and blue. The secondary colors are yellow, cyan and magenta as demonstrated here:
In theory, such combinations should produce black, but produce brown because most commercially available blue pigments tend to be comparatively weaker; [citation needed] the stronger red and yellow colors prevail, thus creating the following tones. The color brown can also be made if multiple paint colors are added to each other.
Blue gold is an alloy of gold and either gallium or indium. [12] Gold-indium contains 46% gold (about 11 karat) and 54% indium, [ 3 ] forming an intermetallic compound AuIn 2 . While several sources remark this intermetallic to have "a clear blue color", [ 2 ] in fact the effect is slight: AuIn 2 has CIE LAB color coordinates of 79, −3.7, − ...
