#E4002B Hex Color

#e4002b is an incredibly high-energy color that overwhelms the eye if used for large backgrounds. Limit it to 10% of your layout, such as for critical buttons, alert icons, or primary calls to action where you need immediate user focus.

Because #e4002b is so aggressive, it needs a neutral anchor to balance its intensity. Pair it with a deep charcoal or a cool, desaturated off-white to ground the vibrancy and make the red feel deliberate rather than chaotic.
