This design shows a deep black rectangle at the center, surrounded by stacked square frames in coral-red, lime green, magenta, violet, light blue, and a thin bright pink edge. In the middle, “Happy Birthday” sits in chunky, pixel-like white letters, giving it an early digital look 🎉. The message feels like a friendly shout across the room, made warmer by the way the bright colors press in close around it. Each square frame is slightly shifted off-center, like layered cutouts leaning toward one another in a cozy, together feel. The strong contrast between the dark core and the neon-like rings makes the greeting stand out fast, like a sign in an arcade. The text stays centered and high-contrast, while the colorful borders form a tight, rhythmic path that pulls your eyes inward 🎂. The outermost frame is coral-red, and the inner frames step down to a narrow bright pink line hugging the black center.
