Heartbeat in blue on a black background
Blue planet with beautiful circles
A flower made of smoke on a blue background
Blue symbol on a black background
Abstract blue flame with a twig inside
Laconic door in black and blue
Landscape of trees and clouds in blue shades
Highlighting the bridge with blue light
The lock glows blue
Blue windows 10 icon on a gray background
Beautiful blue sky with clouds
Bubbles blue brilliant light
