Alleys in Gouache

With a palette of three colors (plus white)

I love to paint in alleys because of the unself-conscious randomness of the setting.

For the one on the left I use a limited palette of titanium white, yellow ochre, burnt sienna, and Prussian blue (also called iron blue).

I choose those pigments because they're enough to mix anything in the scene, and I am guaranteed that the overall effect will be harm…
