Purple is a color intermediate between blue and red. It is similar to violet, but unlike violet, which is a spectral color with its own wavelength on the visible spectrum of light, purple is a composite color made by combining red and blue. According to surveys in Europe and the U.S., purple is the color most often associated with royalty, magic, mystery, and piety. When combined with pink, it is associated with eroticism, femininity, and seduction.

Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the Emperor and aristocracy. The complementary color of purple is yellow.

In culture and society

Asian culture
In China, purple represents spiritual awareness, physical and mental healing, strength and abundance. A red purple symbolizes luck and fame. The Chinese word for purple, zi, is connected with the North Star, Polaris, or zi Wei in Chinese.
In Chinese astrology the North Star was the home of the Celestial Emperor, the ruler of the heavens (As noted above, the area around the North Star is called the Purple Forbidden Enclosure in Chinese astronomy.). For that reason the forbidden city in Beijing was also known as the purple forbidden city (zi Jin cheng).
In Chinese painting, the color purple represents the harmony of the universe because it is a combination of red and blue (yang and yin respectively).
In Japan, purple is the color of privilege and wealth, the color associated with the Japanese aristocracy. The word for purple is murasaki, which is also the name of the purple gromwell flower
Purple was a popular color introduced into Japanese dress during the Heian Period (794–1185). The dye was made from the root of the alkanet plant (Anchusa officinalis), also known as murasaki in Japanese. At about the same time, Japanese painters began to use a pigment made from the same plant.
In Thailand, widows in mourning wear the color purple. Purple is also associated with Saturday on the Thai solar calendar.

Engineering
The color purple plays a significant role in the traditions of engineering schools across Canada. This fascination with purple is commonly attributed to the story of the sinking of the Titanic, in which the purple-clad Marine Engineers remained on board to delay the ship’s sinking. Purple is also the colour of the Engineering Corp in the British Military. It is common for engineers across schools in Canada to dye themselves (and their leather jackets, in the case of Queen’s University engineers) purple using the medical dye Gentian Violet, especially during events such as Frosh Week.
