The document discusses German artist Paul Klee who lived 100 years ago and was friends with Pablo Picasso. He was influenced by Cubism and painted pictures using shapes rather than realistic depictions. Examples of his Cubist style painting "Klee's Cat and Bird" is shown, made up of geometric shapes rather than realistic animals. The text also defines warm colors like red, orange and yellow that are associated with heat sources like the sun and fire, and cool colors like green, blue and purple that are associated with cooler things like water, ice and grass. Readers are instructed to draw shape-based cats like Klee's and color one with warm colors and the other with cool colors.
