Occluded Vestment

#312f78
Notes

Occluded Vestment (#312F78) 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 (242°, 44%, 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 yellow. 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.

Vestment
noun

Latin vestīmentum, garment — adopted into English as the technical term for ecclesiastical liturgical robes, particularly the deep-violet chasuble worn during Advent and Lent in the Roman Catholic and Anglican rites. Vestment color refers to a Roman-Catholic Lenten purple chasuble: a saturated, slightly cool deep blue-violet with the matte finish of vat-dyed liturgical wool-and-silk damask.
