Sooty Tahoe

#28397f
Notes

Sooty Tahoe (#28397F) is a deep blue 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 (228°, 52%, 33%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sooty
adjective

Old English sōt, soot — adjectival suffix -y. As a color modifier, sooty implies the deep-matte-black quality of multi-decade chimney-and-furnace soot-and-creosote-residue surfaces, the Brontë-period Yorkshire-cottage hearth-and-flue patina. Sits at the deep-and-warm end of the grid, parallel to smoky and pitchy.

Tahoe
noun

Lake Tahoe — the deep alpine lake on the California-Nevada border — known for its saturated deep-blue water and clarity (visibility to 21 meters). Tahoe refers to mid-depth Lake Tahoe water on a clear day: a saturated, slightly cool very deep blue with the optical clarity of cold-temperate alpine freshwater.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
