Plainspoken Atacama

#174f8c
Notes

Plainspoken Atacama (#174F8C) is a deep azure 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 (211°, 72%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plainspoken
adjective

English compound plain + spoken — past-participle of speak. As a color modifier, plainspoken implies a clear-and-direct-and-straightforward quality where the hue carries the visual register of unembellished-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Atacama
noun

The Chilean Atacama Desert — and the saturated deep blue of Atacaman lakes (Laguna Verde, Laguna Miscanti) at high altitude in the Andean Altiplano. Atacama refers to Laguna Miscanti at midday: a saturated, slightly cool deep blue with the optical depth of high-altitude desert lake water.
