Luminous Arc Birthday Card

This greeting card features “HAPPY BIRTHDAY” centred in large, raised-looking white letters that appear softly lit, set against a deep indigo background 🎉. A wide rainbow arc frames the text like a gentle embrace, giving the layout a friendly, close-to-the-heart feel. The colour blend moves smoothly from red and orange through yellow and green, then into blue and purple, creating a glowing halo around the words. The lettering sits squarely in the middle while the rainbow curves above and around it, guiding your eyes back to the message. Faint light refractions add a tender sparkle, like two friends sharing a quiet laugh under night sky colours. A slim diagonal beam of light crosses part of the background, adding motion and a little extra celebration 🎂. The overall scene stays dark and starry in tone, with the rainbow and white text standing out sharply, and a soft sheen glinting along the arc’s edges.
