About the Brainstorm black filled icon
A brain drawn from rounded, cloud-like lobes holds a bold lightning bolt at its center, with short rays radiating outward on all sides. It reads as a flash of insight, mental energy and idea generation. Use it in workshop and meeting decks, innovation lab pages, creativity courses, product ideation tools and startup pitch slides.
The bumpy outer edge doubles as a thought cloud, and the evenly spaced rays supply the burst of energy without extra detail. It pairs with lightbulb, mind map and target icons. Keep the rays only above 24 px, or they merge into the outline.
This is the solid black filled version of the brainstorm icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
