Joyful Concentric Birthday Card

This greeting card features a ring of layered circles arranged around a small white rectangle on a bright white background, like a modern paper collage 🎉. The circles range from tiny dots to larger disks, creating a gentle sense of closeness as the shapes seem to lean toward the center together. Colors include rich red, sunny yellow, calm blue, fresh green, and warm orange, spaced so each hue feels like it’s keeping company with the next. In the middle, the message is set on the white rectangle in a simple sans-serif style, centered and easy to read in dark lettering. The surrounding circles form a loose halo, giving the layout a friendly, gathered-together look that reads like a shared celebration 🎂. Soft shadows under each circle and under the center rectangle add depth, as if the pieces were carefully layered by hand. The text sits squarely in the center while the multicolored circles orbit around it in even spacing, with a few smaller accents tucked between the larger shapes. A few of the larger circles appear near the corners, with lighter shadows fading outward across the white space.
