Pleasant Atoll
Pleasant Atoll (#0D8A60) is a deep teal 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 (160°, 83%, 30%) 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
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.
A ring-shaped coral reef enclosing a central lagoon — the geological signature of subsiding volcanic islands ringed by upward-growing coral. Atoll color refers to the unifying blue-green of a Maldivian-style atoll lagoon seen from above: a saturated, slightly cool deep blue-green with the optical clarity of shallow tropical water.
