Pillowed Lithodora

#648e8c
Notes

Pillowed Lithodora (#648E8C) 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 (177°, 17%, 47%) 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

Pillowed
adjective

Old English pyle, pillow — past-participle of pillow. As a color modifier, pillowed implies a hushed-and-cushioned-and-soft quality where the hue carries the visual register of Anglo-Saxon and Norman down-stuffed-and-pillowed bedding-textile soft-finish. Sits at the hushed-and-soft end of the grid, parallel to cushioned and padded in usage.

Lithodora
noun

The genus Lithodora — Mediterranean rock-garden ground covers with intensely deep-blue flowers. L. diffusa 'Heavenly Blue' is among the most saturated blue flowers grown in temperate gardens. The color refers to a fresh L. diffusa mat in flower: a saturated, slightly cool deep blue with the matte finish of small five-petaled flower.
