#515B87 Hex Color

Marlin #515b87 works well for dark interfaces because it provides strong, readable contrast against white or light-colored text while remaining softer and less harsh than pure black. This balance of saturation keeps long-form reading comfortable for user eyes.

To prevent Marlin from appearing too bleak or cold, pair it with warm accents like cream or soft metallic tones. These warm companions ground the cool, gray undertones and create a sophisticated, balanced palette for web layouts or branding.
