How to use this prompt
A thunderstorm logo must balance the cloud and bolt so neither dominates. The electric yellow bolt against dark navy creates maximum contrast, which is essential for a mark that needs to read at app-icon size. Flat vector and thick lines keep it scalable; gradients and thin strokes break down at small sizes.
Variations to try
- Minimal bolt — single yellow lightning bolt for a clean energy icon
- Storm circle — bolt inside a circular cloud badge for a weather app
