Purple
 | This article needs additional citations for verification. (July 2007) |
Purple is any shades of color occurring between blue and red; this color is sometimes confused with the more narrowly-defined spectral color violet.
Properties
On a chromaticity diagram, the straight line connecting the extreme spectral colors (red and violet) is known as the line of purples (or purple boundary); it represents one limit of human color perception. The color magenta used in the CMYK printing process 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 violet is a spectral color.

The color terms purple and violet cause confusion for many people: they are used interchangeably by some people in casual conversation. Technically, purple when used as a general term in its most general sense is the name of the color group of many related colors such as violet, red-violet, heliotrope, lavender, mauve, magenta, rose, indigo and lilac. Indigo is a blue-purple; lilac is a light purple; mauve is between the two. Crayola crayons have many shades of purple; see List of Crayola crayon colors.
Violet is a spectral color of a (approximately 420–380nm) shorter wavelength than blue, while purple is a combination of red and blue light and the shade regarded as electric purple (see below) is one of the three colors on the color wheel (the others being magenta and rose) that are not spectral colors – purple is an extraspectral color, along with magenta and rose. In fact, purple was not present on Newton's color wheel (which went directly from violet to red), though it is present on modern ones. There is no such thing as the "wavelength of purple light"; it only exists as a combination. Also, violet light varies solely by wavelength, while purple varies by the proportion of red to blue light.[citation needed]
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.
One interesting psychophysical feature of the two colors which 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.
The shade of violet shown in the color box is halfway between magenta and blue on the color wheel.
Etymology
The word purple comes from the Middle English word purple which originates from the Latin purpura. This in turn is derived from the (Koine Greek: πορφύρα, porphura) name of the dye manufactured in Classical antiquity from the mucus-secretion of the hypobranchial gland of a marine snail known as the Murex brandaris or the spiny dye-murex.
The first recorded use of the word purple in English was in the year AD 975.[1]
Historical development of purple
The color regarded as the standard for purple changed over the years, from Tyrian Purple in ancient times to Electric Purple today.

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 mollusk that, because of its incredible expense (many times more expensive than gold), in classical antiquity became a symbol of royalty because only the very wealthy could afford it. Therefore, Tyrian purple is 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.[2]

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.
In contemporary times, this shade of purple has been popularized by the rock celebrity Prince, whose fans call him His Purple Majesty. The cartoon girl Gaz on Nickelodeon's Invader Zim has hair of this hue.
Omega Psi Phi, Fraternity Inc., a historically Black Fraternity, Sigma Lambda Beta, a historically Latino Fraternity, and Lambda Chi Alpha have royal purple as one their main colors.

In 1923, the Welch's company began manufacturing Concord grape jelly: [2]. Since for both children and the working class a common food was peanut butter and jelly sandwiches (and Concord grape jelly was and is the cheapest and easiest jelly to mass produce), many people began to think of the dark violet color of grape jelly as purple because that was the most likely way they would encounter the color purple. This shade of purple is known as generic purple. Sometimes it is called vulgar purple.

Royal purple or generic 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.
Artists pigments and colored pencils labeled as purple are colored the red-violet color shown at right.
It seems appropriate that this color should be called "purple" by artists, since it is the closest of all the purples to the original Tyrian purple.

Since using computers, it is possible to create a much brighter purple than with pigment, the equivalent color on a computer to the pigment color red-violet shown above would be 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, it 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 the hippies and it was the favorite color of Jimi Hendrix and therefore it is called psychedelic purple. It is shaded somewhat more toward the magenta than electric purple and it is displayed in the color box at right.
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.

Some people can see electric purple on the spectrum
Ophthalmologists report that those who, for medical reasons, have had their natural lenses removed and replaced with intraocular lenses can see into the ultraviolet and view electric purple on the spectrum beyond violet because the retina has some ultraviolet sensitivity which is normally blocked by the natural crystalline lens. [3] [6]
Purple in human culture

- One of the stars in the Pleiades, called Pleione, is sometimes called Purple Pleione because, being a fast spinning star, it has a purple hue caused by its blue-white color being obscured by a spinning ring of electrically excited red hydrogen gas. [7]
- Purple is generally used to denote a digital video signal in broadcast engineering.
- Purple is associated with Saturday on the Thai solar calendar. Anyone may wear purple on Saturdays and anyone born on a Saturday may adopt purple as their color.
- porpora or purpure was not one of the usual tinctures in European heraldry, being added at a late date to bring the number of tinctures plus metals to seven, so that they could be given planetary associations. The classic early example of purpure is in the coat of the Kingdom of León: argent, a lion purpure as early as 1245.
- Purple has often symbolized royalty, dating back to Roman times, when clothing dyed with Tyrian purple was limited to the upper classes due to the rarity (and thus price) of the dye. The color, which was closer to a deep crimson/red-violet color (shown above) than to the modern idea of purple, was the favored color of many kings and queens.
- Byzantine empresses gave birth in the Purple Chamber of the palace of the Byzantine Emperors. Therefore, being named Porphyrogenitus ("born to the purple") marked a dynastic emperor as opposed to a general who won the throne by his effort.
- In China, the Chinese name of the Forbidden City literally means "purple forbidden city" 紫禁城 with first character 紫 meaning purple(even though the Chinese Emperor himself wore yellow, which was considered in China to be the imperial color).
- Alice Walker, author of The Color Purple, said, "Womanist is to feminist as purple is to lavender."
- As a result of its association with royalty and luxury, the term purple is often used to describe pretentious or overly embellished literature. For example, a paragraph containing an excessive number of long and unusual words is called a purple passage (see Purple prose).
- In April 2007 it was suggested that early archaea may have used retinal, a purple pigment, instead of chlorophyll, to extract energy from the sun. If so, large areas of the ocean and shoreline would have been colored purple; this is called the purple Earth theory. [8]
- In the United States and United Kingdom militaries, purple refers to programs or assignments that are "joint", i. e., that are not confined to a single service such as the Army or Navy, but apply to the entire defense establishment. Assignment to one or more joint billets is required for promotion to flag rank (Rear Admiral and higher) in the U.S. Navy. Officers in joint billets are sometimes referred to as "wearing purple" (the phrase is purely metaphorical as there are no purple uniforms in the U.S. or UK armed forces).
- In politics in the Netherlands, purple (Paars in Dutch) means a government coalition of right-liberals and socialists (symbolized by blue and red, respectively), as opposed to the more common coalitions of the Christian center-party with one of the other two. From 1994 to 2002 there have been two purple cabinets.
- In United States politics, a purple state is a state equally balanced between Republicans (normally symbolized by red) and Democrats (normally symbolized as blue).
- The term porphyrophobia means an irrational fear of the color purple.
- In Christianity purple represents the deadly sin of Pride. [citation needed]
- Robert Burns rhymes purple with "curple" in his Epistle to Mrs. Scott. Burns is, as far as we can tell, the only writer to have used the word. A curple refers to 1) the small of the waist before the flare of the hips or 2) a derriere, rump or behind.
- Today the color purple is also known as a "pride" color among the gay community.
- At the 24 June 2007 San Francisco Gay Pride Parade, Yahoo passed out 3 7/16" in diameter round plastic stickers with a picture of a gay man or woman imaged as one of the Yahoo Gay Pride avatars against an HTML/CSS Purple background that said Out, Proud, and Purple. Yahoo Gay Pride Avatars:
- In the video game World of Warcraft, items of an "Epic" quality (extremely rare items) are the color purple, and are often referred to as "Purples".
