#0100ff is pure electric blue at full saturation. It reads cold, loud, and a little futuristic, closer to a neon than a navy. That intensity makes it a strong accent for buttons, links, and highlights rather than a full background. Pair it with warm amber or soft cream to cut the glare, and set white text on top, which passes contrast at about 8.6:1.
