A 4-by-4 grid of concentric rounded squares alternates between warm gold-yellow and cool avocado-green tones, each nested layer shifting slightly in hue to create subtle depth and visual rhythm. The palette evokes 1970s color sensibilities, while the mathematical precision and symmetrical repetition convey a meditative, almost hypnotic quality that speaks to that era's fascination with op-art geometry. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
