#404C57 Hex Color

Abyssal #404c57 pairs well with white, pale gray, muted blue, and warm accents such as terracotta, which add clarity without overwhelming its dark, dusty blue-gray character. Use lighter companions for highlights, borders, and calls to action.

Abyssal #404c57 reads cool because its blue-gray base and blue undertones outweigh the slight softness created by its muted, ashy saturation, giving the shade a reserved character rather than the warmth associated with brown- or red-leaning grays.

White text on #404c57 provides strong contrast at roughly 8.8:1, meeting WCAG AA and AAA thresholds for normal-sized text; black text has much weaker contrast and is better reserved for lighter tints of Abyssal.
