Easy Cappadocia

#645aa5
Notes

Easy Cappadocia (#645AA5) is a true blue 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 (248°, 29%, 50%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary yellow. 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.

Cappadocia
noun

Central Anatolian volcanic-tuff region in Turkey, famous for its Hittite-era nazar (evil-eye) amulets cast in deep-cobalt-blue glass. Cappadocia color refers to a hand-blown Cappadocian nazar glass disc on a Göreme bazaar stall: a saturated, slightly cool deep blue-violet with the glossy finish of cobalt-and-iron-flux Anatolian glassmaking. Distinct from the same region's pale-tuff stone formations.
