Blue sky, clean air
Glat river blue sky over the bridge
Sea blue and sea foam
Nature. Waters of ponds and streams
Circles and drops on the water. Gradient
Melted ice cubes on a blue background
Water droplets on a red rose
The endless blue sea of Greece
Blue lagoon landscape in the waters of Greece
Romantic table on a deserted beach with white sand and blue sea
A black-and-white snapshot of a nuclear explosion. Nuclear mushroom on the water
Calm waters of the tropical ocean
