Create a vibrant birthday theme background featuring a colorful balloon arch in shades of pink, blue, and gold, with confetti falling gently from the top edges. Include a large, cheerful Happy Birthday banner adorned with streamers across the center. In the foreground, place a beautifully decorated multi-tiered cake with candles lit, surrounded by an assortment of wrapped gifts in various sizes, all set against a soft pastel gradient sky that transitions from light yellow to soft lavender. Add whimsical elements like party hats and playful party blowers scattered around to enhance the festive atmosphere.
