Plain Thor Lagoon

Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.

Old Norse Þórr, god-of-thunder-and-Mjölnir. As a color modifier, thor implies a hammer-Mjölnir-and-thunderbolt-and-red-bearded quality, the visual register of Norse-Thor-and-Mjölnir-hammer hand-hammer-Mjölnir-and-thunderbolt-and-red-bearded Norse-Thor-and-Mjölnir-hammer-and-Asgard thor-and-hammer-Mjölnir-and-thunderbolt surfaces under Norse-Thor-and-Mjölnir-hammer-and-Asgard Bilskirnir-and-Thrudheim-and-thunder-cart thunder-storm-light. Sits at the modifier-and-myth end of the grid, parallel to odin and loki 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.
