Joyful Rainbow 3D Birthday Card

This greeting card features the words “Happy Birthday” centred on a bright white background, set in flowing, rounded lettering that looks slightly inflated and glossy, like coated candy. The letters carry a rainbow blend that shifts from warm reds and oranges through yellow and green into cool blues and deep purple, catching highlights as if light is glancing off curved surfaces. That colour flow gives the design a friendly, upbeat energy 🎉. The phrase sits prominently in the middle, with generous white space around it so the colours stand out without feeling crowded. Scattered around the text are small, shiny spheres in matching rainbow tones, like confetti dots, adding a sense of closeness and shared fun as if friends just tossed them into the air 🎂. The spheres vary in size and appear both above and below the lettering, creating a gentle sense of motion. Each dot has a tiny shadow beneath it, and the glossy highlights make them look like smooth candy beads floating near the words.
