This is a good example of using the opposition colors of Cadmium Red and Thalo blue to achieve a neutral cool or warm dark. This is a night painting done from inside Tom's house.
A nice thing about acrylics is the ability to get back to white by double over-painting with white. I use the jar white because it's more fluid. Because today's whites are made with finely ground titanium instead of coursly ground lead, even the tube white needs two coats to cover completely.
