Plein air 3-4-'11

Yesterday's plein air sketch. Gouache on moleskine sketchbook.

I used only a few colors for this painting:
-Titanium white
-Ultramarine
-Gold ochre (W&N)
-Burnt Umber
-Greenish yellow (talens)
-Turquoise blue

I created most of the painting with only these colors. In the end, I added a few accents with:
-vermillon (traffic lights and the barriers)
-Cad yellow (foliage in the back left)
