Vitreous Pepper Lagoon

#1fa9c8
Notes

Vitreous Pepper Lagoon (#1FA9C8) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (191°, 73%, 45%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Vitreous
adjective

Latin vitreus, glass-like — derived from vitrum (glass). As a color modifier, vitreous implies a clear-and-glassy quality where the hue carries the optical clarity of polished crown-glass. Sits at the crisp-and-clear end of the grid, parallel to pellucid and crystalline in usage.

Pepper
modifier

Latin piper, black-pepper-corn. As a color modifier, pepper implies a black-pepper-corn-and-Malabar-Coast quality, the visual register of Malabar-Coast-and-Vietnamese-pepper hand-black-pepper-corn-and-Malabar-Coast Malabar-Coast-and-Vietnamese-pepper-and-Tellicherry pepper-and-black-pepper-corn surfaces under Malabar-Coast-and-Vietnamese-pepper-and-Tellicherry Malabar-and-Tellicherry-and-Phu-Quoc Indian-Ocean-spice-light. Sits at the modifier-and-flavor end of the grid, parallel to clove and cumin in usage.

Lagoon
noun

A shallow body of saltwater partially or fully enclosed by a barrier — coral atoll lagoons in the Pacific, Venice's Laguna Veneta, the Florida Keys' backcountry. The color refers to the average reflectance of a calm tropical lagoon at midday: a saturated, slightly muted blue-green with the optical clarity of shallow water over white sand. Brighter than reef, cooler than aquamarine, with the postcard weight of a Pacific atoll seen from above.
