A logo / typographic prompt — a clean brand starting point.
Prompt
a soft 3D cartoon-style sculpture of [brand product], made of smooth clay-like textures and vibrant pastel colors, placed in a minimalist isometric scene that complements the product’s nature, clean composition, gentle lighting, subtle shadows, with the product’s logo and a 3-word slogan displayed clearly below
The output stays consistent because the prompt nails down a defined colour grade, so re-running it — or handing it to a teammate — lands in the same place instead of drifting. Keep those clauses and rewrite the subject to make it your own.
