Easy Santorini

#1b5c71
Notes

Easy Santorini (#1B5C71) is a deep cyan 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 (195°, 61%, 27%) 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

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.

Santorini
noun

The volcanic Cycladic island — and the saturated blue of Santorini's caldera water and the cobalt-blue domes of Oia church. Santorini refers to the caldera at sunset: a saturated, slightly cool deep blue with the optical depth of volcanic-bottomed Aegean water.
