Open Wales

#3a5b1f
Notes

Open Wales (#3A5B1F) is a deep lime with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (93°, 49%, 24%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

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.
