Calligraphic Brush Doodle Vector QR Code for Posters

About this design

Flowing navy brush blobs and small coral red flourishes drift across a clean white background, like a page of playful calligraphy doodles. Rounded square frames, two navy and one coral, disguise the finder squares, while the dark modules are carried by thick ink-like curves. Scattered dots, diamonds and leaf shapes fill the gaps with a light ornamental rhythm. The strong navy against white keeps the pattern clear, and the flat vector fills have crisp, simple edges.
