Fortified Wales

#37711d
Notes

Fortified Wales (#37711D) is a deep green 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 (101°, 59%, 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fortified
adjective

Latin fortificāre, to make strong — past-participle of fortify. As a color modifier, fortified implies a saturated-and-strengthened-and-defensive quality, the deep-rich color of Vauban-style military-fortification stone-and-earth rampart-and-bastion architecture. Sits at the bold-and-fortified end of the grid, parallel to bastioned and armored.

Wales
noun

The principality of southwestern Britain — and the saturated green of Welsh hill country, daffodil-and-leek emblems, and the rugby jersey of Crysau Cymru. Wales color refers to a Brecon Beacons hillside at peak spring: a saturated, slightly cool yellow-green with the matte finish of upland pasture.
