Red-violet is a rich color of high medium saturation about 3/4 of the way between red and magenta, closer to magenta than to red. It is classified 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. Both its saturation and brightness falling short of 100%, red-violet is not a pure chroma. There is a color of similar hue that, however, comes close to being a pure chroma: process magenta. The pure chroma color composed of equal parts of magenta and red is called rose. In the use by artists, red-violet is equivalent to purple, however, although the color "purple" is inaccurately used by many people as a synonym for violet or a color close to violet, professional artists who use the RYB color wheel generally use the term "purple" to specifically refer to a pigment color that is equivalent to red-violet (i.e., the tertiary color between violet and red on the RYB color wheel) in order to give themselves a larger and more balanced palette of pigments to work with. The Munsell color system also refers to red-violet as ''purple''; in the Munsell color system, this color at the maximum chroma of 12 is called ''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 color electric magenta for computer displays). ==Relationship of red-violet to other colors== Red-violet is part of the red "analogous color group", which also includes magenta, red, red-orange, orange, gold, and yellow, i.e. those colors classified as "Warm colors", or colors that produces a feeling of warmth (as opposed to "cool colors"). The color that is the complement of red-violet, mint green, lies halfway between green and spring green. It is very close to sea green, but highly saturated, and of a bright hue. In some traditional usage, red-violet is the name given to an intermediate or tertiary color that, along with yellow-orange (gold) and also green-blue (cyan), forms a color wheel triad group. Most contemporary usage, however, would list magenta as the name for the tertiary color in question. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Red-violet」の詳細全文を読む スポンサード リンク
