About the Caution Warning Triangle color outline icon

An equilateral triangle with rounded corners is outlined in red and holds a bold black exclamation mark — a tapered stroke above a round dot — centered on white. It is the universal read for caution, hazard, error and attention required. Use it in form validation and error banners, industrial safety signage, chemical or equipment labels, driver and road-safety apps, and risk sections of presentations.

The thick red border and heavy interior mark give a high-contrast, instantly scannable shape with wide margins inside the triangle. It pairs with info, prohibition and fire hazard signs from the same warning set. Because the color carries the meaning, keep the red saturated and avoid placing it on a red background.

This is the colour outline version of the caution warning triangle icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
