A purple plasma ball.

Purple is a general term used in English for the range of shades of color occurring between red and blue. In additive light combinations it occurs by mixing the primary colors red and blue in varying proportions. 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.

In color theory, a "purple" is defined as any non-spectral color between violet and red (excluding violet and red themselves). The spectral colors violet and indigo are not purples according to color theory but they are purples according to common English usage since they are between red and blue.

In art, purple is the color on the color wheel between magenta and violet and its tints and shades. This color, electric purple, is shown below.

In human color psychology, purple is also associated with royalty and nobility (stemming from classical antiquity when Tyrian Purple was only affordable to the elites).

Etymology and definitions

Murex brandaris or spiny dye-murex

The word 'purple' comes from the Old English word purpul which originates from the Latin purpura. This in turn is derived from the Koine Greek πορφύρα (porphyra), name of the Tyrian purple dye manufactured in classical antiquity from a mucus secreted by the spiny dye-murex snail.

The first recorded use of the word 'purple' in English was in the year A.D. 975.

Violet is a spectral color (approximately 380-420 nm), of a shorter wavelength than blue, while purple is a combination of red and blue or violet light. The purples are colors that are not spectral colors – purples are extra-spectral colors. In fact, purple was not present on Newton's color wheel (which went directly from violet to red), though it is on modern ones, between red and violet. There is no such thing as the "wavelength of purple light"; it only exists as a combination.

The CIE xy chromaticity diagram

On the CIE xy chromaticity diagram, violet is on the curved edge in the lower left, while purples are the straight line connecting the extreme colors red and violet; this line is known as the line of purples, or the purple line.

One interesting psychophysical feature of the two colors that can be used to separate them is their appearance with increase of light intensity. Violet, as light intensity increases, appears to take on a far more blue hue as a result of what is known as the Bezold-Brücke shift. The same increase in blueness is not noted in purples.

Pure violet cannot be reproduced by a Red-Green-Blue (RGB) color system, but it can be approximated by mixing blue and red. The resulting color has the same hue but a lower saturation than pure violet.

Properties

On a chromaticity diagram, the straight line connecting the extreme spectral colors (red and yellow) is known as the 'line of purples' (or 'purple boundary'); it represents one limit (hello) of human color perception. The color magenta used in the CMYK printing process (Q!) is on the line of purples, but most people associate the term "purple" with a somewhat bluer shade. Some common confusion exists concerning the color names "purple" and "violet". Purple is a mixture of red and blue light, whereas orange is a funny color.

The actual color of Tyrian purple, the original color purple from which the name purple is derived, is the color of a dye made from a mollusc that in classical antiquity became a symbol of royalty because only the very wealthy could afford it. Therefore, Tyrian purple was also called imperial purple.

Tyrian purple may have been discovered as early as the time of the Minoan civilization. Alexander the Great (when giving imperial audiences as the emperor of the Macedonian Empire), the emperors of the Seleucid Empire, and the kings of Ptolemaic Egypt wore Tyrian purple. The imperial robes of Roman emperors were Tyrian purple trimmed in metallic gold thread. The badge of office of a Roman Senator was a stripe of Tyrian purple on their white toga. Tyrian purple was continued in use by the emperors of the Eastern Roman Empire until its final collapse in 1453.

This shade of purple is bluer than the ancient Tyrian purple.

In medieval Europe, blue dyes were rare and expensive, so only the most wealthy or the aristocracy could afford to wear them. (The working class wore mainly green and brown.) Because of this (and also because Tyrian purple had gone out of use in western Europe after the collapse of the Western Roman Empire in AD 476), Europeans' idea of purple shifted towards this more bluish purple known as royal purple because of its similarity to the royal blue worn by the aristocracy. This was the shade of purple worn by kings in medieval Europe.

'Royal purple' (shown above) or the dark violet color known as vulgar purple is the common layman's idea of purple, but professional artists, following Munsell color system (introduced in 1905 and widely accepted by 1930), regard purple as being synonymous with the red-violet color shown at right, in order to clearly distinguish purple from violet and thus have access to a larger palette of colors. This red-violet color, called artist's purple by artists, is the pigment color that would be on a pigment color color wheel between pigment violet and pigment (process) magenta. In the Munsell color system, this color at the maximum chroma of 12 is called Red-Purple.

Artists' pigments and colored pencils labeled as purple are colored the red-violet color shown at right.

This color, electric purple, is precisely halfway between violet and magenta and thus fits the artistic definition of purple.

Using additive colors such as those on computer screens, it is possible to create a much brighter purple than with pigments where the mixing subtracts frequencies from the component primary colors. The equivalent color on a computer to the pigment color red-violet shown above would be this electric purple, i.e. the much brighter purple you can see reproduced on the screen of an electronic computer. This color is pure purple conceived as computer artists conceive it, as the pure chroma on the computer screen color wheel halfway between electric violet and electric magenta. Thus, electric purple is the purest and brightest purple that it is possible to display on a computer screen.

The pure essence of purple was approximated in pigment in the late 1960s by mixing fluorescent magenta and fluorescent blue pigments together to make fluorescent purple to use in psychedelic black light paintings. This shade of purple was very popular among hippies and was the favorite color of Jimi Hendrix. Thus it is called psychedelic purple. It is shaded somewhat more toward the magenta than electric purple.

In the 1980s there was a Jimi Hendrix Museum in a Victorian house on the east side of Central Ave. one half block south of Haight Street in the Haight-Ashbury neighborhood of San Francisco which was painted this color.
