Open Vela Lagoon

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

Latin vela, sails-of-the-Argo. As a color modifier, vela implies a southern-hemisphere-and-Argo-sail-and-supernova-remnant quality, the visual register of Vela-supernova-remnant-and-Argo-sails hand-southern-hemisphere-and-Argo-sail-and-supernova-remnant Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way vela-and-southern-hemisphere-and-Argo-sail surfaces under Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way Southern-Cross-and-southern-zenith southern-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to cygnus and draco 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.
