About the Warning color outline icon
A rounded triangle drawn with a double outline surrounds a bold exclamation mark and dot, the universal symbol for caution. It signals errors, hazards, risky actions or important notices that need attention. Use it for form validation messages, error banners, safety signage, road warning signs, app alerts and dashboard status indicators.
The thick double border gives the triangle extra visual weight so it reads clearly at small sizes. It pairs well with error, alert and notice icons in the set. Keep it at 24px or larger so the exclamation mark stays legible.
This is the colour outline version of the warning 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.
