Maroon sits in the warm red family, with the hex code #800000 mapping to rgb(128, 0, 0) in RGB and hsl(0, 100%, 25.1%) in HSL. In OKLCH it carries 38% perceptual lightness and 0.155 chroma — a highly saturated, dark reading that behaves well as a primary, accent or decisive colour in modern interfaces. Red is the most physiologically arousing hue — it raises heart rate, sharpens attention and signals urgency. Designers reach for it when a screen needs to feel decisive, appetising or emotionally charged.
