In modern color theory, red, green and blue are the additive primary colors, and together they make white. A combination of red, green and blue light in varying proportions makes all the colors on your computer screen and television screen.
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. The name of the model comes from the initials of the three additive primary colors , red, green, and blue.
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 test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full hue spectrum are also present.
Pigment red is the color red that is achieved by mixing process (printer's) magenta and process (printer's) yellow in equal proportions. This is the color red that is shown in the diagram located at the bottom of the following website offering tintbooks for CMYK printing: Tintbooks - Get Accurate CMYK Color Results For Your Printing Projects.
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. [3]
For example, mixing red and yellow can result in a shade of orange, generally with a lower chroma or reduced saturation than at least one of the component colors. In some combinations, a mix of blue and yellow paint produces green. This occurs when there is sufficient transparency in the pigments, allowing light to penetrate into the mixed ...
Despite this, many color theorists have devised formulae, principles or guidelines for color combination with the aim being to predict or specify positive aesthetic response or "color harmony". Color wheel models have often been used as a basis for color combination guidelines and for defining relationships between colors. Some theorists and ...
