In the Western Culture, the color purple is a symbol of wealth and royalty. People that rule places are often seen wearing the color purple. It is sometimes seen as artificial because it isn't often seen in nature.
Purple is also the color of mourning widows in Thailand. It was also a color of mourning in the U.S. and England -- used by more distant family members or at later stages of mourning for close members (such as widows after 1 year). Because of this use purple and lavender, which was also used, are sometimes considered unlucky colors.
Purple is sometimes associated with spirituality. This is because purple, or violet, is at the top of the color spectrum. Of the colors in the visible spectrum, it is the one that vibrates at the highest frequency. Some people believe that when we become more spiritual, we too raise the rate at which we vibrate. Purple, or violet, is associated with the seventh chakra, located at the crown of the head. This is the chakra of connection to spirit.
The Bisexual Community uses purple as a symbol because it is between pink, symbolic of homosexuality, and blue, for heterosexuality.
Purple is the colour used to symbolize the sin of pride.
