"Good guess," Trish said. "Van Gogh did want paintings to express his emotions. But he still went outside and painted things as they really were, more or less. True Expressionists abandoned natural colors and realistic subjects in order to devote themselves to expressing their emotions. In fact, Expressionists used such shocking colors that they were nicknamed "fauves" or "wild beasts.". Rouault, for example, used savage, slashing brushstrokes and unnatural colors."
