Muted Birthday Rainbow Card

This greeting card features a simple illustration with a gentle celebratory mood 🎉. A softly arched rainbow sits in the centre, drawn in muted earthy bands like blush pink, terracotta, mustard yellow, and dusty blue on a creamy off-white background. The colours feel calm and cosy, like a quiet moment shared between close friends. Near the top, the words “Happy Birthday” are placed above the rainbow in deep teal lettering, standing out clearly against the light backdrop. The lettering has smooth, flowing strokes that add a tender, affectionate touch without crowding the design. Plenty of open space around the artwork keeps the layout airy and relaxed, letting the eye rest on each element. Beneath the innermost curve of the rainbow, a tiny crimson heart sits centred as a sweet focal point 🎂.
