Red-violet

Red-violet refers to a rich color of high medium saturation about 3/4 of the way between red and magenta, closer to magenta than to red.^[1] In American English, this color term is sometimes used in color theory as one of the purple colors—a non-spectral color between red and violet that is a deep version of a color on the line of purples on the CIE chromaticity diagram.^{[citation needed]}

In use by some artists red-violet is equivalent to purple. Since violet and purple vary so much in meaning when comparing speakers from different countries and languages, there is much confusion.^[2][3]

The Munsell color system includes the hue term purple, and for some (especially US) speakers of English at the maximum chroma of 12, this refers to 'Red-Purple". This convention is for chromatic purposes, since Red-Purple lies between violet and printer's magenta (the color regarded as magenta before the invention of the web color magenta for computer displays).^{[citation needed]}
