Joyful Teal 3D Birthday Card

This card features a deep teal background with gentle shading that adds depth and a calm party atmosphere 🎉. Centred on the front, the large text reads “HAPPY BIRTHDAY!” in thick, raised-looking letters with shaded edges that make them feel almost touchable. The letter colours shift across warm coral red, sunny yellow, and cheerful orange, with a small touch of cool blue-grey on a few characters for contrast. The words sit squarely in the middle of the design, standing out clearly against the darker backdrop. Above the message, two curved strings of small triangular pennants sweep across the top, as if hanging overhead at a cosy get-together with close friends. The pennants echo the same warm colours as the lettering, creating a friendly, together-in-the-moment feel without adding extra clutter. Soft shadows under the letters and flags suggest gentle overhead lighting, like a room set for cake and candles 🎂. Two arched rows of multicolored triangle flags sit above the centred “HAPPY BIRTHDAY!” text on the teal field.
