"Square poster — minimal color-blocking style, flat vector shapes, lots of negative space. Central shiny disco ball made of simple geometric facets (no photo texture) reflecting bold blocks of summer colors: warm coral, sunset orange, pale pink, teal, and sunny yellow. Large circular disco ball centered, slightly above middle; beneath it, a clean, modern sans-serif headline placeholder: '45' (all caps). Add smaller line for details: Keep composition balanced and airy, limited palette (4–5 colors), high contrast, crisp edges, no gradients, minimal icons (small palm leaf or sun silhouette optional). Deliver as bright, playful, minimal vector art, 2048x2048, PNG with transparent background option." Mehr sehen
