#33578A Hex Color

White text reads best on Dark Cobalt Blue, hitting about 7.3:1 contrast, which clears the 4.5:1 WCAG AA standard for small body text. Dark text on this shade falls below that threshold, so stick with light type.

Dark Cobalt Blue flatters warm, muted accents like terracotta, amber, or dusty rose, which offset its cool gray undertones. Cool blues and teals tend to blend in rather than contrast.
