Expressionism is an artistic style focused on emotional and spiritual expression over physical realism. Vincent Van Gogh and Edvard Munch used expressionism to explore their own voices and feelings in a hostile world where they felt insecure. Munch's painting "The Scream" expresses his own cry of loneliness and fear, depicting a bloody red sky that made him feel trembling fright. Van Gogh's "Sunflowers" showed how he used intense color to express his feelings about a subject rather than simply describe it, opening our eyes to the expressive power of color.
