The composition features clean, bold shapes and a limited retro color palette of muted pastels and rich tones like cream, and deep blue. A simplified badminton racket and shuttlecock are central elements, with sleek, geometric lines and smooth curves creating a sense of elegance and balance. The badminton court is suggested with subtle, abstract patterns or blocks of color, while the text is set in a bold, sans-serif or art deco-inspired font, perfectly complementing the retro vibe.
