Red Orange
A high-energy, vibrant red orange burst

Red Orange is a saturated, high-energy hue that demands immediate attention. Because it is so loud and aggressive, the hex code #ff3f34 works best as a 10% accent color for calls to action or alert indicators rather than a primary background. Pair it with dark grays or deep navies to ground its intensity, as black text provides the most legible contrast for this bright shade.
