Mournful Vasilek

#555c77
Notes

Mournful Vasilek (#555C77) is a true blue 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 (228°, 17%, 40%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mournful
adjective

Old English murnan, to grieve — adjectival suffix -ful. As a color modifier, mournful implies a hushed-and-grieving-and-sad quality where the hue carries the visual register of Victorian-mourning widow's-weeds-and-funeral-procession mourning-and-grieving textile-finish. Sits at the hushed-and-melancholy end of the grid, parallel to plaintive and doleful in usage.

Vasilek
noun

The Russian word for cornflower (Centaurea cyanus) — and the saturated bright blue of cornflower fields among Russian wheat. Vasilek-blue is the unifying field-flower color of Russian rural summer. The color refers to a fresh cornflower at peak bloom in a Russian wheat field: a saturated, slightly cool bright blue.
