"Craft a minimalist stained glass background that subtly celebrates St. Patrick's Day, employing a palette of modern pastel colors to evoke a fresh and appealing atmosphere. Instead of making it the centerpiece, incorporate a delicate four-leaf clover motif into the design as an accent, blending seamlessly with other geometric shapes or abstract patterns. This approach will ensure the essence of the holiday is captured through a sophisticated and understated aesthetic, perfect for a chic and contemporary interpretation of St. Patrick's Day symbolism."
