Magenta (colour)

Magenta is a colour that sits between red and blue, commonly described as a dark red with blue in it. It is also called by other names such as fuchsia, particularly when referring to computer displays.

Magenta plays an important role in colour mixing systems. As one of four colours in standard printing, it works in the technological system by which colour is produced on both paper and screen.

How the colour is created

In the RGB (red, green, blue) light system, magenta is created when red and blue light are mixed together while green is absent. For this reason, magenta is described as the colour opposite to green: if green is removed from white light, magenta remains.

In the CMYK printing system, magenta is one of three primary colours — cyan (blue-green), magenta, and yellow — combined with black. Printers layer these colours to produce other hues.

History of the name

The name 'magenta' is linked to the town of Magenta in northern Italy, after which a dark red chemical dye was named in the 19th century. This synthetic dye replaced colours previously extracted from plants and expanded the use of the textile industry.

Light and distinctive properties

Magenta has a particular characteristic: it does not exist in the optical spectrum of light (rainbow). Other colours such as red, green, and blue each have their own wavelength, but magenta is created only by mixing the two ends of the spectrum. For this reason, some describe it as a colour that the brain produces when the eyes receive red and blue light together.

Use

In printing, magenta is used in business signs, textiles, and network design. It is also commonly used as a marker to show colour quickly to the eye, because it is not abundant in the natural environment.
