Colorful Circles Psychedelic Vector QR Code for Posters

About this design

A crowd of overlapping circles, concentric rings and looping brush lines in yellow, red, pink and cyan fills a deep navy field. Two square frames with round centers, one in a pink-orange ring and one in a striped blue frame, disguise the finder squares, while clusters of dark dots and rings carry the modules. Navy gaps and dark circles against the bright fills keep the pattern readable. The flat vector shapes feel like a record sleeve from a retro festival.
