Plumb Sari Lagoon

#418087
Notes

Plumb Sari Lagoon (#418087) 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 (186°, 35%, 39%) 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

Plumb
adjective

Latin plumbum, lead — referring to the lead-weighted plumb-line of pre-modern carpentry. As a color modifier, plumb implies a clear-and-vertical-true quality where the hue carries the visual register of gravity-aligned-and-perfectly-vertical surface. Sits at the crisp-and-balanced end of the grid, parallel to level and squared in usage.

Sari
modifier

Sanskrit śāṭī, long-draped-cloth. As a color modifier, sari implies an Indian-sari-and-Banarasi-and-Kanjeevaram-silk quality, the visual register of Banarasi-and-Kanjeevaram-sari hand-Indian-sari-and-Banarasi-and-Kanjeevaram-silk Banarasi-and-Kanjeevaram-sari-and-Mysore-and-Bengal-cotton sari-and-Indian-sari surfaces under Banarasi-and-Kanjeevaram-sari-and-Mysore-and-Bengal-cotton Varanasi-and-Kanjeevaram-and-Mysore-loom Indian-loom-light. Sits at the modifier-and-textile end of the grid, parallel to kimono and haori 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.
