Tidy Malt Lagoon

#13bddf
Notes

Tidy Malt Lagoon (#13BDDF) 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 (190°, 84%, 47%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Tidy
adjective

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

Malt
modifier

Old English mealt, germinated-grain. As a color modifier, malt implies a kilned-grain-and-amber-stout quality, the visual register of Burton-on-Trent-and-Bavarian-malt hand-kilned-grain-and-amber-stout Burton-on-Trent-and-Bavarian-malt-and-Munich-and-Pilsen malt-and-kilned-grain surfaces under Burton-on-Trent-and-Bavarian-malt-and-Munich-and-Pilsen Burton-and-Munich-and-Pilsen brewery-and-kiln-light. Sits at the modifier-and-flavor end of the grid, parallel to syrup and zest 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
