This mobile phone wallpaper seems to be a blue movement composed by the vast ocean, and every note represents the endless depth and mystery of this ocean. The undulating waves on the sea surface are like high and low notes in a movement, staggered but orderly. The soft form of the clouds in the sky adds a touch of grace to the movement. The color of the whole work is mainly blue, from the deep blue water to the light blue sky, like the transition from bass to treble, playing a harmonious song of the ocean. This wallpaper is not only visually beautiful, but also makes people feel the tranquility and grandeur of nature.
