Red, green and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue.

The color displayed at right, RGB red or electric red (i.e., as opposed to pigment red, shown below) is the brightest possible red that can be reproduced on a computer screen. This color is an approximation of spectrum red. 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.

This color is also called color wheel red. It is at precisely 0 (360) degrees on the HSV color wheel, also known as the RGB color wheel (Image of RGB color wheel:). Its complementary color is cyan.

This color is also the color called red in the X11 web colors, which were originally formulated in 1987.

Additional definitions of red

Red (CMYK) (pigment red)

Cyan, magenta, and yellow are the three subtractive primary colors used in printing.

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: [1].

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 that is possible on a computer screen) the electric red shown above.

Red (NCS) (psychological primary red)

Red (NCS)

Hex triplet		#C40233
sRGBB	(r, g, b)	(196, 2, 51)
HSV	(h, s, v)	(345°, 99%, 77%)

B: Normalized to [0–255] (byte)

Approximations within the sRGB gamut to the primary colors of the Natural Color System, a model based on the opponent process theory of color vision.

The color defined as red in the NCS or Natural Color System is shown at right (NCS 1080-R). The Natural Color System is a color system based on the four unique hues or psychological primary colors red, yellow, green, and blue. The NCS is based on the opponent process theory of vision.

The “Natural Color System” is widely used in Scandinavia.

Red (Munsell)

The hues of the Munsell color system, at varying values, and maximum chroma to stay in the sRGB gamut.

The color defined as red in the Munsell color system (Munsell 5R) is shown at right. 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.
