ISCC–NBS descriptor. Vivid reddish orange. B: Normalized to [0–255] (byte) 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.
Red is any of a number of similar colors evoked by light, consisting predominantly of the longest wavelengths discernible by the human eye, in the wavelength range of roughly 625–750 nm. It is considered one of the additive primary colors .
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan.
Byte 1: red value (color type red) Byte 2: green value (color type green) Byte 3: blue value (color type blue) Byte 4 (optional): alpha value; For example, consider the color where the red/green/blue values are decimal numbers: red=36, green=104, blue=160 (a grayish-blue color).
Hexadecimal 8-bit RGB representations of the main 125 colors. A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet ( r, g, b ), each component of which can vary from zero to a defined maximum value.
The IALA recommends categorical color codes in 7 colors: red, orange, yellow, green, blue, white & black. Adding redundant coding of luminosity and colorfulness adds information and increases speed and accuracy of color decoding tasks. Color codes are superior to others (encoding to letters, shape, size, etc.) in certain types of tasks.

ROYGBIV. The conventional gradient colors of the rainbow symbol. ROYGBIV is an acronym for the sequence of hues commonly described as making up a rainbow: red, orange, yellow, green, blue, indigo, and violet.
Iron oxide red is a generic name of a ferric oxide pigment of reddish colors. Multiple shades based on both anhydrous Fe. 2O. 3 and its hydrates were known to painters since prehistory. The pigments were originally obtained from natural sources, since the 20th century they are mostly synthetic.
