Sunshine on the Creek

Create more interesting color in a summer green landscape by letting the eye mix the colors.  If all you see is a sea of green allow the eye to mix the colors rather than get out a tube of green paint and add white to lighten it and black to darken it.  Take advantage of the blues and purples in the shadows and the oranges and yellows in the light to bring interest to the scene.  The green areas can range from light yellow green to dark blue green.

The dappled light coming through the trees creates interesting patterns in the water.
