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.
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.
The primaries cyan, magenta and yellow combine pairwise to produce subtractive secondaries red, green, and blue. Combining all three primaries (center) absorbs all light and produces black. In practical CMY color models, the center is usually dark gray and a separate black pigment is required to produce black (CMYK model).
In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of colored inks. To save cost on ink, and to produce deeper black tones, unsaturated and dark colors are produced by using black ink instead of or in addition to the combination of cyan, magenta, and yellow.
The combination of two of the common three additive primary colors in equal proportions produces an additive secondary color—cyan, magenta or yellow. Additive color is also used to predict colors from overlapping projected colored lights often used in theatrical lighting for plays, concerts, circus shows, and night clubs.
Magenta is the complement of green, and yellow the complement of blue. Combinations of different amounts of the three inks can produce a wide range of colors with good saturation. In inkjet color printing and typical mass production photomechanical printing processes, a black ink K (Key) component is included, resulting in the CMYK color model ...
To form a color with RGB, three light beams (one red, one green, and one blue) must be superimposed (for example by emission from a black screen or by reflection from a white screen). Each of the three beams is called a component of that color, and each of them can have an arbitrary intensity, from fully off to fully on, in the mixture.
Each wire is identified by the combination of two colors, one of which is the major color, and the second the minor color. ... blue/black 11 36 black/blue orange ...
