Frank Thor Lagoon

#2eb5d1
Notes

Frank Thor Lagoon (#2EB5D1) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (190°, 64%, 50%) 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

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

Thor
modifier

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.

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.
