Cooling Anchusa

#457176
Notes

Cooling Anchusa (#457176) 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 (186°, 26%, 37%) 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

Cooling
adjective

Old English cōl, cool — present-participle of cool. As a color modifier, cooling implies a hushed-and-tone-reducing-and-cooling quality where the hue carries the visual register of evening-dusk gradually-cooling atmospheric-light color-temperature shift. Sits at the hushed-and-soft end of the grid, parallel to softening and quieting in usage.

Anchusa
noun

The genus Anchusa — Mediterranean borage-family perennials with saturated deep-blue flower spikes used in Renaissance European herbal medicine. The color refers to a fresh A. azurea (Italian bugloss) flower spike: a saturated, slightly cool deep blue with the matte finish of small five-petaled forget-me-not-style flowers.
