Easy Akhdar

#256b65
Notes

Easy Akhdar (#256B65) is a deep cyan 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 (175°, 49%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Easy
adjective

Old French aisié, comfortable, at rest — used as a color modifier since the eighteenth century for hues that read as visually undemanding. Easy beige, easy gray: moderate saturation combined with optical restfulness. Sits at the crisp-bucket center alongside calm and settled.

Akhdar
noun

The Arabic word for green — used for the deep green of the Khidr (the Green One) in Islamic mysticism, the green domes of mosques, and the Jabal al-Akhdar (Green Mountain) of Oman. The color refers to a Saudi mosque-dome glaze: a saturated, slightly cool deep green with the high gloss of fired ceramic glaze.
