Plain Thoth 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.

Egyptian Djehuty, ibis-headed-god-of-writing. As a color modifier, thoth implies an ibis-headed-and-scribe-and-moon-god quality, the visual register of Egyptian-Thoth-and-Hermopolis-temple hand-ibis-headed-and-scribe-and-moon-god Egyptian-Thoth-and-Hermopolis-temple-and-Hermes-Trismegistus thoth-and-ibis-headed-and-scribe-and-moon-god surfaces under Egyptian-Thoth-and-Hermopolis-temple-and-Hermes-Trismegistus papyrus-and-reed-pen-and-Hermopolis ibis-scribe-light. Sits at the modifier-and-myth end of the grid, parallel to isis and horus 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.
