Notes
Red in CSS is #ff0000, the brightest possible red the sRGB color space can produce. The hex is too saturated for almost any practical UI use except as a brief error state or attention flag. Cultural associations are unusually strong: danger, passion, urgency, importance. Real-world red branding usually pulls a slightly desaturated or darker variant. The pure value functions strictly as a visual stop signal; for sustained use, Crimson, Firebrick, or a modern OKLCH-tuned red will hold up better. Body text contrast against white falls below AA at body sizes.
