use outline to define a non - representational two - dimensional organic shape. Use one color for the outline and another for the shape. Arrange a series of geometric shapes to create an implied line. Use a type of line described in the textbook as dynamic to direct attention. Use different colors to contrast these lines with placid and assertive lines. Create an implied shape consisting of four figures and an empty ground. Use two different colors to play with our perception of figure and ground, like Escher or the Ancient Puebloan potter.Draw
