Varieties of the color red may differ in hue, chroma (also called saturation, intensity, or colorfulness) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors are shown below.

Red (RGB), RGB red, or electric red[citation needed] (as opposed to pigment red, shown below) is the brightest possible red that can be reproduced on a computer monitor. This color is an approximation of an orangish red spectral color. It is one of the three primary colors of light in the RGB color model, along with green and blue. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum gamut of colors that are capable of being represented on a computer or television set, at a reasonable expense of power. Portable devices such as mobile phones might have an even narrower gamut due to this purity–power tradeoff and their "red" may be less colorful and more orangish than the standard red of sRGB.
This color is also the color called red in the X11 web colors, which were originally formulated in 1987. It is also called color wheel red. It is at precisely zero (360) degrees on the HSV color wheel, also known as the RGB color wheel (Image of RGB color wheel). Its complementary color is cyan.
Red (CMYK) (pigment red)
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: .
The purpose of the CMYK color system is to provide the maximum possible gamut of colors capable of being reproduced in printing.
Psychedelic art made people used to brighter colors of red, and pigment colors or colored pencils called "true red" are produced by mixing pigment red with a tiny amount of white. The result approximates (with much less brightness than is possible on a computer screen) the electric red shown above.
Red (Crayola)
The color is defined as red in Crayola crayons.
Red was one of the original colors formulated by Crayola in 1903.

The color is defined as red in the Munsell color system (Munsell 5R). The Munsell color system is a color space that specifies colors based on three color dimensions: hue, value (lightness), and chroma (color purity), spaced uniformly in three dimensions in the elongated oval at an angle shaped Munsell color solid according to the logarithmic scale which governs human perception. In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five primary colors—red, yellow, green, blue, and purple.
The Munsell colors displayed are only approximate as they have been adjusted to fit into the sRGB gamut.
