Concentric arcs of teal, pink, yellow, and coral radiate outward from a central void, creating a symmetrical tunnel of color that recalls retro graphic artwork from mid-century Americana. The lines sit cleanly against a warm cream ground, their even spacing and gentle curves evoking both a rainbow and the optimistic geometric vocabulary of vintage California aesthetics. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
