Pleasant Alpine

#0f647b
Notes

Pleasant Alpine (#0F647B) 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 (193°, 78%, 27%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Pleasant
adjective

From the French plaisant, pleasing — used as a color modifier since the fifteenth century for hues that read as agreeable, the kind of color that wears well over a long viewing without becoming demanding or fatiguing. Pleasant green, pleasant rose: moderate saturation combined with optical comfort. Sits at the crisp-bucket alongside easy and calm.

Alpine
noun

Of the Alps, the European mountain range — and the saturated blue of Alpine lake water (Lake Geneva, Lake Como, Lake Brienz) fed by glacier-melt. Alpine color refers to Lake Brienz at midday: a saturated, slightly cool deep blue with the optical clarity of glacier-fed alpine lake water.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
