Purple is not part of the visible color spectrum:

In the strict sense, there is no visible light of its own for the color purple; it is the perception that arises when red and blue light are mixed.

The history of purple

is tied to its extreme cost and exclusivity, originating from Tyrian purple dye made from sea snails by the Phoenicians around (1200) BC. This dye was so expensive that it became a status symbol for royalty and the elite in ancient Rome and the Byzantine Empire. The color's association with power and wealth shifted in 1856 when an accident led to the creation of the first synthetic purple dye, making it more accessible to the public and later adopted by movements like women's suffrage.
