Magenta () is a color that is variously defined as pinkish-purplish-red, reddish-purplish-pink or mauvish-crimson. On color wheels of the RGB (additive) and CMY (subtractive) color models, it is located exactly midway between red and blue. It is one of the four colors of ink used in color printing by an inkjet printer, along with yellow and cyan, to make all other colors. The tone of magenta used in printing is called "printer's magenta". It is also a shade of pink. Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it fuchsine. It was renamed to celebrate the Italian-French victory at the Battle of Magenta fought between the French and Austrians on 4 June 1859 near the Italian town of Magenta in Lombardy. A virtually identical color, called roseine, was created in 1860 by two British chemists, Edward Chambers Nicholson and George Maule. The web color magenta is also called fuchsia. In optics and color science Magenta is an extra-spectral color, meaning that it is not a hue associated with monochromatic visible light. Magenta is associated with perception of spectral power distributions concentrated mostly in two bands: longer wavelength reddish components and shorter wavelength blueish components. In the RGB color system, used to create all the colors on a television or computer display, magenta is a secondary color, made by combining equal amounts of red and blue light at a high intensity. In this system, magenta is the complementary color of green, and combining green and magenta light on a black screen will create white. In the CMYK color model, used in color printing, it is one of the three primary colors, along with cyan and yellow, used to print all the rest of the colors. If magenta, cyan, and yellow are printed on top of each other on a page, they make black. In this model, magenta is the complementary color of green, and these two colors have the highest contrast and the greatest harmony. If combined, green and magenta ink will look dark gray or black. The magenta used in color printing, sometimes called process magenta, is a darker shade than the color used on computer screens. In terms of physiology, the color is stimulated in the brain when the eye reports input from short wave blue cone cells along with a sub-sensitivity of the long
