So one of the other reactions to World War I senselessness, was an explosion of colors in Expressionism. Artists came to use color in distorted matter away from realistic skin tones to symbolic colors in their art. One of the artists to define the movement is Franz Marc using vivid colors in his art. In this work you can see the horse portrayed in blues perhaps to symbolize sadness in his character. There are parallels to Neo-impressionism as well with exaggerated colors. Many artists continue to use this artificial colors to enhance the features in portrait artworks vs. traditional skin tones. I tend to prefer it to the traditional skin tones of academic work. In my own work, I use vivid color in my abstract art styles, but I don't think it would technically qualify for expressionism.
