A picture of the Brooklyn Bridge against a background of blue sky and water with riverboats and a city in the distance
The surface of the Earth with satellites and glow on the background of blue space
The glow of blue and scarlet in the boundless space among the planets and stars
Planet Earth and satellite Moon on the background of blue and green glow in space
Catalina hydroplane flies against the background of blue water
Clouds illuminated by the rays of the sun, on a background of blue sky
