Orderly Glassy

#21583d
Notes

Orderly Glassy (#21583D) 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 (151°, 45%, 24%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Orderly
adjective

Latin ōrdō, order — adjectival suffix -ly. As a color modifier, orderly implies a clear-and-arranged-and-organized quality where the hue carries the visual register of carefully-ordered-and-classified placement. Sits at the crisp-and-orderly end of the grid, parallel to methodical and organized in usage.

Glassy
noun

A descriptor for very calm water surface — used in maritime vocabulary for sea conditions when wind is below 1 knot and the surface reflects like polished glass. Glassy color refers to a glassy-calm tropical lagoon at dawn: a saturated, slightly cool deep blue-green with the mirror-finish optical complexity of unbroken water.
