This card features a soft, pale yellow banner gently arcing across the middle, setting a cozy tone for a friendly celebration 🎉. Centered on the banner, the words “Happy Birthday” appear in a flowing green lettering style that feels like a warm note shared between close friends. Behind it, vertical stripes in leafy greens, cool teals, and creamy off-white create a calm, outdoorsy backdrop that suggests easy companionship. The stripe edges subtly wave rather than staying straight, adding a relaxed, affectionate energy like a shared laugh. A faint shadow beneath the yellow banner gives it a light lift from the background, adding depth without looking heavy. The text sits squarely in the center of the banner, with the green color standing out clearly against the pale yellow. The overall palette stays gentle and balanced, mixing cool and warm tones in a way that feels inviting 🎂. The stripes run from top to bottom with softly uneven edges in alternating green, teal, and off-white bands.
