Drawn Diatom

#3b8272
Notes

Drawn Diatom (#3B8272) is a true teal 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 (166°, 38%, 37%) places it in the balanced 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 red. 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.

Diatom
noun

Single-celled algae with intricate silica cell walls — among the most numerous photosynthetic organisms on Earth, producing roughly a quarter of global oxygen. The color refers to a diatom-bloom-tinted lake at midday: a soft, slightly cool deep blue-green with the optical complexity of suspended single-celled algae.
