Magenta is an [[spectral color#Extra-spectral colors|extra-spectral color]], meaning that no [[Spectral color|color of the visible spectrum]] has magenta's hue. Magenta is associated with perception of [[spectral power distribution]]s concentrated mostly in two bands: longer wavelength reddish components and shorter wavelength blueish components.<ref>{{cite book |last1= Parkin |first1=Alan |title=Digital Imaging Primer |date=2015 |publisher= Springer Science & Business Media |isbn=978-3540856191 |page=278 |url= https://books.google.com/books?id=dRacCgAAQBAJ&pg=PA278}}</ref>

Magenta is the [[complementary color]] of green; thus, mixing one specific shade of magenta light and one specific shade of green light will result in white light.

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 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. If combined, magenta ink plus ink of its complementary color, green, will result in a dark brown or black.

In terms of [[physiology]], the color is stimulated in the brain when the eye reports input from short wave blue [[cone cell]]s along with a sub-sensitivity of the long wave cones which respond secondarily to that same deep blue color, but with little or no input from the middle wave cones.  The brain interprets that combination as some hue of magenta or purple, depending on the relative strengths of the cone responses.

In the [[Munsell color system]], magenta is called ''red-purple''.
