Color - BLUE - Sky, Water, and Mountains

The color Blue is the foundation color for landscapes and seascapes.  My palette contains 5 colors of blue: Cerulean, Cobalt, Ultramarine, Peacock, and Royal.  My color chart is shown below with a dark, medium, and light value mixture of pigment and water.  Blue mixes with all the other colors in the palette to cool down a bright color and mix a variety of beautiful grays.

The landscape above has all the colors of blue used in different areas.

• The sky is a mixture of wet-on-wet Cobalt Blue and Cerulean Blue. Leaving some white paper for the clouds and light red for the sunset color. 
•  The water is a mixture of Cerulean Blue and Peacock Blue.  Leaving some white paper for the waves and red color from the sky.  The colors of the water are reflections of the sky colors. 
• The mountains colors are a dark mixture of Ultramarine Blue and Royal Blue with touches of Hooker's Green, Burnt Sienna, and Red. This makes a variety of dark colors.  Some white paper is left to indicate a reflection off a structure or something.  This gives an interest to the dark colors. 
• The foreground beach and palm tree are painted with Ultramarine Blue, Burnt Sienna and Hooker's Green.
