Indigo Brush Calligraphy Ink QR Code for Posters

About this design

Bold brush calligraphy characters in indigo and rust red scatter across a warm cream ground, with small red seal stamps tucked between the strokes. Three navy square frames, each holding an orange circle with a carved glyph, disguise the finder squares. The remaining modules are carried by the thick ink strokes and brush flourishes, which sit dark against the pale background. Strong contrast and the even spread of heavy strokes keep the pattern clear, while thin accent characters add a handwritten feel.
