Basalt

Basalt (#2F3533) is a deep neutral with a mono character. It's a grayscale value, at home in typography, dividers, and the structural layer beneath stronger colors. Its HSL profile (160°, 6%, 20%) places it in the muted band at a dark lightness. It works as a background, hairline border, or text color in dark UI. Swap to true black when you need maximum contrast. Pair it with almost any saturated accent. It's built to sit underneath or behind stronger colors without fighting them. The near-black of cooled basaltic lava, the most common volcanic rock on Earth's surface. It covers the ocean floor and Iceland's Reynisfjara beach, where it weathers into hexagonal columns.
