Warm Helichrysum

#556c22
Notes

Warm Helichrysum (#556C22) is a deep lime 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 (79°, 52%, 28%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Warm
adjective

Old English wearm, of moderate heat — used as a color modifier since the medieval period for hues that read as containing red, orange, or yellow undertones. Warm gray, warm white: not necessarily a temperature, but the optical impression of a slight red-orange shift. Sits across the crisp and neutral buckets.

Helichrysum
noun

The genus Helichrysum — Mediterranean composite-family plants whose dried yellow flower bracts retain their color for years (also called strawflower). The color refers to dried Helichrysum bracts in a winter bouquet: a soft, slightly muted dry yellow with the matte papery finish of preserved flower.
