Steady Halcyon

#a8f2d5
Notes

Steady Halcyon (#A8F2D5) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (156°, 74%, 80%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

Halcyon
noun

The Greek mythological bird of calm seas — and the modern genus Halcyon of Old World kingfishers. Halcyon days names the seven days before and after winter solstice when, according to Greek myth, the halcyon bird nested on calm seas. The color refers to a male Halcyon kingfisher's head: a saturated, slightly cool deep blue-green.
