Welcoming Slab Lagoon

Old English wel-cuman, well-coming — present-participle of welcome. As a color modifier, welcoming implies a clear-and-inviting-and-warm quality where the hue carries the visual register of cordial-and-hospitable color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to hospitable and inviting in usage.

Old French esclape, splinter / slab. As a color modifier, slab implies a flat-thick-stone-or-wood quality, the visual register of Cotswold-and-Yorkshire-flagstone-and-slab hand-quarried-and-flat-thick stone-and-timber-and-marble hand-quarried-flat-thick-slab surfaces under Cotswold-and-Yorkshire flagstone-and-slab quarry-light. Sits at the modifier-and-texture end of the grid, parallel to plate and tile in usage.

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.
