"After Impressionism, painting went in many different directions. All kinds of "isms" sprang up - Symbolism, Fauvism, Cubism, Abstract Expressionism, and Futurism, just to name a few. Realism went back to the Tonalist method of painting, and later the personalized method of Wyeth, which is a Tonalist approach. Then there is the Photo Realist and the Super Realist which focus more on the technique of literally copying a photograph or a projected slide.

     No one took what Monet and the Impressionists had introduced to the world and applied it to a Color Visualist concept. This Color Visualist concept is based on a color difference for each plane change according to the light key. The Tonalist uses different values from the local color to represent the plane changes. History began to write Impressionism off as a movement that exhausted all that could be done with light and color.

      This view is far from being true. It is through the teaching of Charles Webster Hawthorne and later his student and assistant Henry Hensche that this view is disproved.

     Charles Hawthorne was the first painter in the history of painting to put the "Impressionist concept of seeing" into a teaching principle. Hawthorne spent the last fifteen years of his life trying to understand what Monet looked for and how he painted. Henry Hensche, an assistant to Hawthorne, perfected the concept of seeing and teaching color after Hawthorne's death in 1930. Mr. Hensche taught and practiced this visual language of color from that first Summer in 1930 until his death in 1992."
