Famous artists and painter, Manet, describes the true color of the atmosphere as “violet”. He says “fresh air is violet. Three years from now, the whole works will work in violet”.
Violet is also known as the color of the Impressionists. You might wonder why though, it's not exactly a prominent color in most of their paintings.
The first reason it is named this is because of the way the Impressionists use violet in their paintings of shadows. They were the first group of artists to believe that shadows of objects were not just grey, but included color. They used violet because it was the complimentary color to yellow which was used in a majority of their paintings.
In addition, violet was the color of the Anonymous Society of Painters, Sculptors, Print Makers like Degas, Monet, Cezanne, etc.
I mean it's so cool to think that violet has such deep roots in the history of art and how such principles carry over into today's art making!
