Cerulean
As the Colorado River extends south of Las Vegas and wanders through the Mojave Desert, it pauses and widens to form Lake Mohave. There the cerulean pigment is brushed out of the shallows of the pooling river into the gently sloping desert. The colors on the distant aerial horizon blend similarly. Though not through brush strokes, they are blended by the radiant effect of light diffusing in the atmosphere. The palette of the desert is more diverse than one would imagine and it grows more varied as we look deeper into the landscape. The blue, green, yellow, and orange pigments pop out of the landscape as we look down on Mount Tipton on the eastern bank of the Colorado.
