Far from a soft pastel, #3181dd is a bold, saturated blue with real punch. Its vivid mid-tone reads confident rather than calm, so it works best as an accent, button, or link color instead of a full background. Muted neighbors make it pop; the guide on what colors make gray helps you mix them. Black text passes contrast at about 5.3:1, so small body copy stays readable.
