Crisp Bluejay

#618c9b
Notes

Crisp Bluejay (#618C9B) 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 (196°, 23%, 49%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Crisp
adjective

Latin crispus, curled — drifted in English from the curled hair sense to fresh and clean. As a color modifier, crisp implies saturation combined with optical clarity, with no haze or film between the eye and the surface. Used across the bright and crisp buckets where the hue is fresh-looking. Slightly less assertive than vivid.

Bluejay
noun

Cyanocitta cristata, the North American blue jay — a corvid with saturated blue back, wing, and tail feathers. The blue is structural color (light scattering off feather barbs), not pigment. The color refers to a male blue jay's wing covers: a saturated, slightly cool deep blue with the iridescent satin finish of structural feather color.
