Occluded Khorasani

#3a1b42
Notes

Occluded Khorasani (#3A1B42) is a deep violet 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 (288°, 42%, 18%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Occluded
adjective

Latin occludere, to close up — past-participle of occlude. As a color modifier, occluded implies a hue blocked-and-dimmed by an intervening physical barrier. Sits at the deep-and-obscured end of the grid, parallel to eclipsed and cloaked but more clinical in register.

Khorasani
noun

Persian خراسانی, Khorasani-style — the long-historical Iranian region of Khorasan whose Safavid-period silk weavers produced the deep-purple imperial textiles for the Mughal courts of India. Khorasani color refers to a Safavid Khorasan-school silk qaba coat: a saturated, slightly cool deep violet with the silk luster of multi-bath gromwell-root-and-indigo overdye on woven Iranian silk.
