Pleasant Glare Lagoon

#3f8c9c
Notes

Pleasant Glare Lagoon (#3F8C9C) is a true cyan 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 (190°, 42%, 43%) 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

Pleasant
adjective

From the French plaisant, pleasing — used as a color modifier since the fifteenth century for hues that read as agreeable, the kind of color that wears well over a long viewing without becoming demanding or fatiguing. Pleasant green, pleasant rose: moderate saturation combined with optical comfort. Sits at the crisp-bucket alongside easy and calm.

Glare
modifier

Middle English glaren, to-shine-brightly. As a color modifier, glare implies a harsh-and-bright-and-overwhelming quality, the visual register of desert-noon-and-snow-field-glare hand-harsh-and-bright-and-overwhelming desert-noon-and-snow-field-and-salt-flat glared-and-harsh-and-bright-and-overwhelming surfaces under desert-noon-and-snow-field-and-salt-flat overhead-sun-and-snow-blind-and-bleached harsh-noon-light. Sits at the modifier-and-mood end of the grid, parallel to flash and blaze 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.
