Magenta (/məˈdʒɛntə/) is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On computer screens, it is made by mixing equal amounts of blue and red. On color wheels of the RGB (additive) and CMY (subtractive) color models, it is located midway between red and blue. It is the complementary color of green. It is one of the four colors of ink used in color printing and by an inkjet printer, along with cyan, yellow, and black, to make all the other colors. The tone of magenta used in printing is called "printer's magenta" (Magenta (CMYK)).

Magenta was first introduced as the color of a new aniline dye called fuchsine, patented in 1859 by the French chemist François-Emmanuel Verguin. Its name was changed the same year to magenta, to celebrate a victory of the French and Sardinian army at the Battle of Magenta on June 4, 1859, near the Italian town of that name.

The web color magenta is also called fuchsia.

Magenta is an extra-spectral color, meaning that it is not found in the visible spectrum of light. Rather, it is physiologically and psychologically perceived as the mixture of red and violet/blue light, with the absence of green.
