Symbolism of the Color Green
The word green is closely related to the Old English verb growan, “to grow.” Green is the color of life. It is the color of seasonal renewal. Since verdant spring triumphs over barren winter, green symbolizes hope and immortality. The Chinese associate green (and black) with the female Yin - the passive and receiving principle. Islam venerates the color green, expecting paradise to be full of lush vegetation. Green is also associated with regeneration, fertility, and rebirth due to its connections with nature.
In Alchemy, solvents for gold were named "Green Lion" or "Green Dragon" by the alchemists. Such liquids were instrumental in the beginning of the alchemistic Opus Magnum. Transparent green crystal symbolized the "secret fire," which represented the living spirit of substances.
In some cultures, green symbolizes hope and growth, while in others, it is associated with death, sickness, or the devil. It can also describe someone who is inexperienced, jealous, or sick.
Short History of Green Pigments
In painting (substructive color system), green is not a primary color, but is created by mixing yellow and blue. Green pigments have been used since Antiquity, both in the form of natural earth and malachite, used primarily by Egyptians. Greeks introduced verdigris, one of the first artificial pigments. Copper resinate was introduced in European 15th century easel panting, but was soon discarded. Thanks to chemistry, a new generation of greens was introduced beginning in the late 18th century: cobalt green, emerald green, and viridian.
The perception of green occurs with light at wavelengths of roughly 520–570 nm.
