Joyful Birthday Rainbow Heart Card

Designed with a large, stylised heart at the centre, the artwork draws you in with a glossy gradient that moves from bright pink to deep purple. The heart is sprinkled with small white and pale yellow dots and edged with a strong black outline, giving it a graphic, modern look. Around it, sharp rays spread outward in rainbow slices—reds and oranges shifting into greens and blues—like a celebratory burst 🎉. The white background is dotted with tiny pink and blue hearts, sunny yellow stars, and small flower shapes in primary colours, arranged like little notes of affection floating nearby. Soft shadows under these mini shapes add a sticker-like depth, as if they’re gently hovering in the space between friends. A short line of text sits near the top in a simple uppercase style, set in dark lettering that stands out against the light background 🎁. Off to one side, a curved multicolor trail arcs away from the burst and ends in a golden star.
