Affable Tūsī

#13122a
Notes

Affable Tūsī (#13122A) 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 (243°, 40%, 12%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Affable
adjective

Latin affābilis, easy-to-speak-to — adjectival suffix -able. As a color modifier, affable implies a neutral-and-friendly-and-approachable quality where the hue carries the visual register of Edwardian-and-American-Country friendly-and-welcoming-hosting interior-decoration-and-textile coordinated-color tone. Sits at the neutral-and-friendly end of the grid, parallel to amiable and cordial in usage.

Tūsī
noun

Persian طوسی, Tūs-style gray — named after the Tūs region of Khorasan, whose Safavid-period silk-weavers produced the iron-gray qaba coats for the Mughal courts. Tūsī color refers to a Safavid Tūs-school silk qaba coat: a dark gray with the silk luster of multi-bath iron-tannin-and-charcoal overdye on woven Iranian silk.
