How to use this prompt

Spiral shell logos rely on the Fibonacci-like curve to feel natural. Smooth curved segments keep it modern rather than scientific. Coral and sand feel beachy and premium. The 1:1 frame is ideal for app icons. The spiral should open outward in a clockwise direction for a calm reading. Avoid too many segments; five or six are enough.

Variations to try

  • Minimal shell — single thin spiral line for a luxury spa mark
  • Shell with pearl — small circle inside for a jewelry brand
