Here are the first two pages of my Playing with Paint experiment. The page on the left is base coated with grey Gesso and then layered with a yellow acrylic wash. I then used dark ochre and yellow oil sticks to add dimension.
The page of the right was based coated with black Gesso. It was then layered with a watered down Kelly green acrylic that was then wiped off with paper towels. A green and dark ochre oil stick was used to give it dimension.
