Black background for phone — vibrant rainbow cascade

A glossy stream of liquid in rainbow gradient colors drips vertically down a solid black background, with tiny bubbles suspended inside the fluid. This dark design is ideal for AMOLED and OLED panels because the black pixels switch off to save battery life. Formatted in high resolution with a 9:16 aspect ratio, the graphic fits your screen without cropping. Get this beautiful black background for phone now as a free download.
