This greeting card features a shower of glossy, jewel-toned spheres clustered against a deep midnight-blue background, like confetti caught midair for a birthday 🎉. The orbs range through soft pink, teal, tangerine, sunny yellow, and lavender, each with a glassy shine that catches small highlights. Their close, tumbling arrangement feels like friends leaning in together, creating an affectionate sense of togetherness through the way the colors mingle and overlap. Gentle, diffused lighting adds smooth gradients and rounded shadows, giving the spheres a candy-like look without feeling harsh. In the upper center, the words “Happy Birthday” sit over the cluster in flowing white lettering that stands out clearly from the darker backdrop 🎂. Behind everything, faint circles of light float like distant party lights, echoing the same colors and adding depth. The dark blue background is sprinkled with soft bokeh dots that shimmer around the edges of the sphere cluster.
