#11353f - Firmament Blue color
A very deep teal-blue, almost like the shadowed surface of a northern sea at dusk. It reads cool and muted, with green undertones that give it an evergreen, maritime character rather than a pure navy. The shade feels sophisticated and grounding—subtle and moody rather than bright—making it excellent for backgrounds, accents in interiors, branding for premium or nautical themes, and elegant contrasts with warm metals, creams, or coral highlights.
