Step 4 Paint the sky with light portrait pink, yellow oxide, and magenta—thinned with gloss medium. Add blue as you paint closer to the horizon. Use the same mix to paint reflected color on the walls. Darken the shadows in the foreground of your painting by with purple, magenta, Prussian blue, and raw sienna, suggesting tiles. Add light blue-violet to the wall.
