Pleasant Artemisia

#66a59c
Notes

Pleasant Artemisia (#66A59C) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (171°, 26%, 52%) 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 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.

Artemisia
noun

The genus Artemisia — sage-and-wormwood-and-mugwort relatives whose silver-green leaves define Mediterranean dry-garden landscaping. The color refers to a fresh Artemisia ludoviciana cultivated in a Provençal garden: a soft, slightly cool gray-green with the matte velvet finish of pubescent silver leaf.
