Hemmed Olmec Lagoon

#38bcd4
Notes

Hemmed Olmec Lagoon (#38BCD4) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (189°, 64%, 53%) 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

Hemmed
adjective

Old English hem, border — past-participle of hem. As a color modifier, hemmed implies a clear-and-finished-and-bordered quality where the hue carries the visual register of carefully-hemmed-and-finished textile-edge. Sits at the crisp-and-finished end of the grid, parallel to trim and finished in usage.

Olmec
modifier

Nahuatl Ōlmēcatl, rubber-people. As a color modifier, olmec implies a pre-Classic-Mesoamerican quality, the visual register of Olmec-civilization-of-La-Venta pre-Classic Mesoamerican hand-carved colossal-head-and-jade-and-pottery archaeological surfaces under La-Venta-and-San-Lorenzo pre-Classic Mesoamerican Gulf-coastal humid light. Sits at the modifier-and-cultural end of the grid, parallel to aztec and toltec 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.
