How to use this prompt
"Flat spotlights as triangles" is the technique — naming the spotlights as geometric primitives is what keeps the stage lighting in the flat-design vocabulary; the model otherwise renders light beams with gradient falloff that breaks the flat aesthetic. "Geometric audience silhouettes as dark shapes along the bottom" is the crowd cue — a flat band of dark shapes reads as an audience without any individual detail; naming them as silhouettes stops the model from rendering faces. "Limited to four flat colours" is the palette cap — concert posters in flat design use a tight palette for graphic impact; extra colours dilute the poster feel. Keep the guitar and drum kit as simple shapes so they read as icons.
Variations to try
- Swap the guitar for a grand piano shape for a jazz concert variant
- Change the palette to neon pink and electric blue for a synthwave concert version
