Pleasant Woad

#31a4a6
Notes

Pleasant Woad (#31A4A6) 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 (181°, 54%, 42%) places it in the balanced 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.

Woad
noun

Isatis tinctoria, the European blue-dye plant whose leaves yield indigo-equivalent indigotin. Used by Pictish warriors as body paint and the dominant pre-industrial European blue dye until East Indian indigo displaced it in the seventeenth century. The color refers to a freshly woad-dyed wool: a saturated, slightly cool deep blue with the matte finish of plant-and-mordant dye.
