Step Two!

Start adding the distant hills using soft purple and blue.  As you move toward the front, brighten the colors with more green and gold.  Add some lighter areas to show sunlight, keeping the direction of the sun in mind.  In this painting, the sun is shining from the left, so I highlighted the left slopes of the hills.  Have fun with color!  Tuscany has wheat fields, poppies, vineyards, so make those hills colorful!
