Infused Atacama

#143a7b
Notes

Infused Atacama (#143A7B) 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 (218°, 72%, 28%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Infused
adjective

Latin infundere, to pour into — past-participle of infuse. As a color modifier, infused implies a deep-pigment-and-warmth where the hue has been filled from within with the source dye. Sits at the deep-and-saturated end of the grid, parallel to suffused and steeped 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.
