Design an elegant invitation card background featuring a soft watercolor wash gradient in pastel shades of blush pink, lavender, and mint green. Layer delicate gold foil elements, such as floral patterns and whimsical swirls, subtly intertwined throughout the design. Incorporate a slight texture that mimics handmade paper, and allow for ample negative space in the center to accommodate personalized text. The overall aesthetic should evoke a sense of sophistication and warmth, suitable for a refined gathering or celebration.
