The blue of the sea and the beautiful underwater world
The Blue River between the glaciers of Greenland
A tall palm tree against the blue sky
The nature of the mountain is a reflection of the blue sky in the water
The blue surface of the lake reflects the fabulous flamingos
Serene rock in the blue kingdom
Boundless expanses of the blue element
Paradise clean tropical beach against the blue sky
Trees against the blue sky
A pair of dolphins swim in the blue ocean
Bright jellyfish in the blue ocean
Airplane wing in the blue sky
