Luminous Festive Birthday Card

The front design shows a deep, near-black background that makes every glowing element stand out like a night celebration 🎉. A neon frame wraps the edges, shifting from hot pink to cool blue-green, guiding your eye towards the centre. On the right side, four glossy balloon-like spheres float upward on thin, shimmering strings, their surfaces catching highlights like they’re leaning close together in friendly company. Each sphere has its own rich colour—purple, golden yellow, orange, and deep blue—adding depth and a gentle sense of togetherness. Across the upper and middle area, firework-style bursts flare in teal, rosy pink, and warm amber, with tiny sparks scattered around them like shared excitement in the air. Near the lower portion, the words “Happy Birthday” appear in glowing pink lettering, centred and easy to spot 🎂. The neon border remains brightest at the corners, fading smoothly along the sides into the dark background.
