Have you ever been really, really angry? What did you look like when you were angry? Give them time to demonstrate what they looked like. If you had to imagine that your anger was a certain color, what color would it be?
What about happy or sad? Sometimes artists use color and line to tell us about mood—or emotions—even in landscape.
