Modest Gloam Lagoon

#0bb5d0
Notes

Modest Gloam Lagoon (#0BB5D0) 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 (188°, 90%, 43%) 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

Modest
adjective

Latin modestus, moderate — used as a color modifier since the sixteenth century for hues that read as understated and unwilling to claim more visual space than they need. Modest taupe, modest beige: moderate-to-low saturation combined with optical restraint. Sits at the crisp-and-quiet edge of the grid alongside quiet and plain.

Gloam
modifier

Old English glōm, twilight-or-dusk. As a color modifier, gloam implies a twilight-and-half-light-and-fading quality, the visual register of Scottish-Border-and-Hebridean-gloam hand-twilight-and-half-light-and-fading Scottish-Border-and-Hebridean-and-Orkney gloamed-and-twilight-and-fading surfaces under Scottish-Border-and-Hebridean-and-Orkney long-northern-twilight-and-blue-hour gloaming-and-twilight light. Sits at the modifier-and-mood end of the grid, parallel to dusk and shade 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.
