Cool Sand- 1 part Alizarin Crimson and two parts Yellow Ochre , a touch of Cerulean Blue, take this colour to the white. This is for far away sand off in the distance.
Warm Sand — equal parts of Cadmium Red and Cadmium yellow with a touch of Utramarine Blue than take this colour to the white and lighten. Should be a very pale, sunshine colour of sand.
Shadows of the grass and posts– Alizarin Crimson and Ultramarine Blue in equal parts with a touch of Yellow Ochre. Put these colours down and then soften with a clean brush.
Dune Grass– Cadmium yellow and French Utramarine Blue with just a touch of Alizarin Crimson to tone down the green. This is the dark shades of grass. Leaving just a bit of green on your brush, dip into the Cadmium yellow and add as highlights.
