Pleasant Iceberg

#51808f
Notes

Pleasant Iceberg (#51808F) is a true 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 (195°, 28%, 44%) 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 orange. 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.

Iceberg
noun

Floating freshwater ice — calved from glaciers and ice shelves — characterized by the saturated pale blue of the underwater portion. The blue comes from the same Rayleigh scattering that colors the sky, intensified through compressed glacier ice. The color refers to a freshly calved Antarctic iceberg's underwater face: a saturated, slightly cool pale blue.
