Refreshing Lithodora

#3694cd
Notes

Refreshing Lithodora (#3694CD) is a true azure 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 (203°, 60%, 51%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Refreshing
adjective

Old French refreschir, to make fresh again — present-participle of refresh. As a color modifier, refreshing implies a clear-and-cool-and-revitalizing quality, the crisp color of Cornish-coast and Hebridean-island fresh-sea-air-and-cool-water revitalization. Sits at the crisp-and-cool end of the grid, parallel to fresh and bracing 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.
