The fifth sessions of the Trihue Watercolor class for Winter 2018 were held on Wednesday, February 14 and Sunday, March 4. The film and veil homework was critiqued. The new topic is white light and shadow. You need shade to create the illusion of light. In white light, a cast shadow is a gray (transparent black) film. To paint shadows in watercolor, paint the local colors first, then apply the shadow wash over them. Or, since watercolors are transparent, lay down the shadows first and paint the local colors over.
