Rainbow concentric circle design poster

Rings of colour pulse outward in alternating warm and cool bands — sunset orange and gold, salmon pink, deep periwinkle, spring green — circling out from a single glowing magenta centre like a heartbeat frozen mid-beat. This rainbow concentric circle design carries a groovy, retro-70s energy with a hypnotic, almost meditative pull, finished with a soft grainy texture for a vintage-poster feel. It's a bold geometric wall art piece for anyone who wants their space to feel a little more alive: a maximalist, feel-good statement for retro lovers, boho-eclectic homes, dorm rooms, and fans of psychedelic pattern art and mandala-inspired decor.
