Candid Nautilus

#28723b
Notes

Candid Nautilus (#28723B) is a deep green 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 (135°, 48%, 30%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Candid
adjective

Latin candidus, bright-white / honest — derived from candēre (to shine). As a color modifier, candid implies a clear-and-honest-and-direct quality where the hue carries the visual register of straightforward-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to frank and plainspoken in usage.

Nautilus
noun

Nautilus pompilius, the chambered nautilus — a living-fossil cephalopod whose mother-of-pearl interior shell is the source of abalone-style iridescence. Nautilus color refers to the inner shell of a polished nautilus: a soft, slightly cool pale blue-green with the iridescent satin finish of nacreous biomineral.
