Magenta, a bright pinkish purple color, is a color evoked by lights with less power in green wavelengths than in blue and red wavelengths (complements of magenta have wavelength 500–530 nm). In light experiments, magenta can be produced by removing the lime-green wavelengths from white light. It is an extra-spectral color, meaning it cannot be generated by a single wavelength of light, being a mixture of red and blue wavelengths. The name magenta comes from the dye magenta, commonly called fuchsine, discovered shortly after the 1859 Battle of Magenta near Magenta, Italy.

In the Munsell color system, magenta is called red-purple. In the CMYK color model used in printing, it is one of the primary colors of ink. In the RGB color model, the secondary color created by mixing the red and blue primaries is called magenta or fuchsia, though this color differs in hue from printer’s magenta.
