Tomblike Sumi

#131627
Notes

Tomblike Sumi (#131627) 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 (231°, 34%, 11%) 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

Tomblike
adjective

Greek tymbos, tomb — adjectival suffix -like. As a color modifier, tomblike implies the deep-and-funereal-and-sepulchral quality of Etruscan-and-Egyptian rock-cut royal-tomb interiors, particularly the Valley-of-the-Kings and Cerveteri-necropolis hand-carved chamber-painting walls. Sits at the deep-and-funereal end of the grid, parallel to sepulchral and crypted.

Sumi
noun

Japanese ink stick, made from soot of pine resin or sesame oil mixed with animal-glue binder, used in sumi-e brush painting and shodō calligraphy. Although nominally black, undiluted sumi on rice paper carries a deep blue-violet undertone. Sumi color refers to a heavily-loaded sumi brushstroke: a saturated, slightly cool deep blue-violet with the matte finish of pine-soot ink on absorbent washi.
