Stern Mallorca

#09283b
Notes

Stern Mallorca (#09283B) 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 (203°, 74%, 13%) 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

Stern
adjective

Old English styrne, strict / firm — sharing root with stark. As a color modifier, stern implies a deep-and-uncompromising quality, the dark formal-Calvinist plain-textile color of stripped-down Protestant-and-Quaker tradition. Sits at the deep-and-formal end of the grid, parallel to austere and severe in tone.

Mallorca
noun

The largest Balearic island — and the saturated deep blue of Mallorcan Tramuntana coastline at Cala Tuent and Sa Calobra. Mallorca color refers to the cove water at Sa Calobra: a saturated, slightly cool deep blue with the optical depth of cold-water Mediterranean cove against limestone cliff.
