Foreboding Scarlet

#642931
Notes

Foreboding Scarlet (#642931) is a deep red 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 (352°, 42%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Foreboding
adjective

Old English fore-bēodan, to announce in advance — present-participle of forebode. As a color modifier, foreboding implies a deep-and-threatening atmospheric-anticipation quality, the dark cool-gray of advancing-cyclone storm-front cumulonimbus-base. Sits at the deep-and-threatening end of the grid, parallel to ominous and menacing in atmospheric tone.

Scarlet
noun

From the medieval Latin scarlatum, originally a fine wool cloth rather than a color — the dye came later when the fabric was associated with the bright red of kermes-stained textiles. The defining red of British military uniforms, fox-hunt coats, and The Scarlet Letter. Hotter than crimson, less orange than vermillion: a pure, attention-demanding red.
