About the No Idea Sign Bulb color filled icon
A solid light bulb with a filament and screw base sits inside a bold ring, cancelled by a diagonal bar running corner to corner. It reads as no idea, creative block, a rejected suggestion or ideas not allowed. Use it in brainstorming and innovation slides, writer's-block or burnout articles, feature-disabled states, quiz and hint systems, and error or empty-state illustrations.
The prohibition ring is heavy and the slash cuts across the bulb at 45 degrees, so the negation stays obvious even in one flat color. It pairs with the plain light bulb, idea, question mark and warning icons. Use the crossed bar at full contrast; at 16 px it can blend into the bulb outline.
This is the colour filled version of the no idea sign bulb icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
