Purple is a range of hues of color occurring between red and blue. In additive light combinations it occurs by mixing the primary colors red and blue in varying proportions. It is a secondary color because two colors (blue and red) make up this color. In subtractive pigments it can be equal to the primary color magenta or be formed by mixing magenta with the colors red or blue, or by mixing just the latter two, in which case a color of low saturation will result. Low saturation will also be caused by adding a certain quantity of the third primary color (green for light or yellow for pigment). There is a disagreement over exactly which shades can be described as purple, some people preferring more precise terms such as magenta or heliotrope for particular shades. A difference in retinal sensitivity to red and blue light between individuals can cause further disagreement. See Less
