Central Cathedral

#0d1d18
Notes

Central Cathedral (#0D1D18) is a deep teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (161°, 38%, 8%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Central
adjective

Latin centrālis, central — adjectival suffix -al. As a color modifier, central implies a neutral-and-central-and-balanced quality where the hue carries the visual register of Mid-Century-Modern and Bauhaus central-and-balanced-and-grounded foundational-design fundamental-element. Sits at the neutral-and-foundational end of the grid, parallel to core and grounded in usage.

Cathedral
noun

The interior color of an aging Gothic cathedral — limestone darkened by centuries of candle smoke, incense, and city soot. The color refers to the upper walls of Notre-Dame de Paris before the 2019 fire and restoration: a soft, slightly muted dark gray with the matte finish of weathered porous stone. Cooler than smoke, warmer than slate, with the architectural weight of a building type whose interiors are read primarily in shadow.
