Drawn Nautilus

#3a6a4c
Notes

Drawn Nautilus (#3A6A4C) 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 (143°, 29%, 32%) places it in the muted 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

Drawn
adjective

Old English dragan, to draw — past-participle of draw. As a color modifier, drawn implies a clear-and-line-and-mark quality, the crisp color of Old-Master-and-Modernist hand-drawn studio-and-life-class observational-drawing graphite-and-charcoal lines. Sits at the crisp-and-incised end of the grid, parallel to etched and drafted 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.
