Clouds over the blue sea in calm
The sky is blue and the heat is over the yellow surface
Blue sky during winter
Aspen trees looking into the autumn blue sky
Deep blue sea at sunset
Blue lake with yellow autumn leaves
High mountains and blue lakes
Beautiful clouds over the blue ocean
Beautiful view of the water with rocks protruding from it, blue sky and red trees in the distance
Blue Night sky with moon and stars
A green palm tree against a blue sky
White snow, blue river on the background of mountains
