Designed with a floating cluster of heart-shaped balloons painted in soft watercolor washes, this card sets a sweet, affectionate scene 🎉. Warm and cool colors mingle across the hearts—deep red, orange, sunny yellow, leafy green, sky blue, and light purple—each one shaded to look plush and gently rounded. Thin dark strings drop from the hearts and gather together, as if drawn close like friends leaning in for a photo. Near the bottom of the strings, a small red ribbon is tied into a neat bow, adding a quiet romantic touch. The background stays bright white, letting the colors feel airy and letting the hearts stand out. Centered below the artwork, the words “Happy Birthday” appear in a deep charcoal tone, with the text placed low on the front for balance 🎂. A few tiny heart accents are scattered around the lettering, echoing the balloon shapes and adding little points of warmth in the open space. The bow sits just above the message, with the strings converging into a tidy knot beneath the hearts.
