About the Warning Exclamation Diamond Sign color outline icon
A diamond outlined in bright red frames a bold black exclamation mark, drawn as a tapered stroke above a round dot. The layout copies standard road and GHS hazard signage, so it communicates caution, risk and required attention. Use it for safety instruction sheets, chemical and product warning labels, construction site notices, form validation and error states in apps, and alert banners on dashboards.
The rotated square sits point-up with even margins, and the exclamation mark is centered with generous white space on both sides, which keeps the shape legible even as a tiny badge. Down to 16px the diamond and mark still read. Pair it with info, error, prohibition and biohazard icons for a complete notice set, and keep the red at full saturation on light backgrounds.
This is the colour outline version of the warning exclamation diamond sign 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.
