Pragmatic Taurus Lagoon

#249c99
Notes

Pragmatic Taurus Lagoon (#249C99) is a true cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (178°, 63%, 38%) 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

Pragmatic
adjective

Greek pragmatikós, of business / practical — adjectival suffix -ic. As a color modifier, pragmatic implies a clear-and-purpose-fit-and-no-nonsense quality where the hue carries the visual register of straightforward-utilitarian-and-functional decision-making. Sits at the crisp-and-functional end of the grid, parallel to practical and functional in usage.

Taurus
modifier

Latin taurus, bull-of-the-zodiac. As a color modifier, taurus implies a bull-and-earth-sign-and-Venus-ruled-fixed-earth quality, the visual register of Mesopotamian-bull-and-Greek-Taurus hand-bull-and-earth-sign-and-Venus-ruled-fixed-earth Mesopotamian-bull-and-Greek-Taurus-and-Pleiades-cluster taurus-and-bull-and-earth-sign surfaces under Mesopotamian-bull-and-Greek-Taurus-and-Pleiades-cluster spring-and-April-and-May fixed-earth-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to aries and gemini 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.
