About the Danger color outline icon
A red equilateral triangle with softly rounded corners frames a thick exclamation mark, the international shape for hazard, caution and attention. It communicates risk, urgency and a need to stop and read. Use it for form validation and error states in web apps, safety notices on machinery and packaging, construction and road signage, alert banners in dashboards, and risk slides in training decks.
The triangle is drawn as an even outlined band that leaves the center open, so the solid exclamation stem and its separate dot stay readable when scaled down. It sits naturally beside prohibition circles, biohazard marks and information badges. Keep it at 20px or larger so the dot does not disappear.
This is the colour outline version of the danger icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
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.
