Goal: Create a Landscape painting using a Grisaille Underpainting Technique
Edgar Payne said, "A really good painting requires 'color vibration,' where each color feeds off one another. An undertone assures that one color is sensed all over the piece pulling the work together.
Use an underpainting tone then paint a complementary based color scheme on top.
A red underpainting will enhance the greens of nature to vibrate and energize yet pull the work together harmoniously.
