Dunes with blue sand on a blue background
A lonely cloud in the blue sky
Blue balloon in the blue sky
Favorite place on the shore of a beautiful lake
Blue grass and trees against a brown sky with white clouds
A school of blue fish in the ocean
A blue frog is sitting on a green leaf
Lots of transparent blue jellyfish
Blue butterfly next to pink flowers
A whirlpool of blue water and a fish
Blue butterfly on a dry leaf
Big-billed parrot of blue color
