Folded Niloo

#0a4e8b
Notes

Folded Niloo (#0A4E8B) is a deep azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (208°, 87%, 29%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Folded
adjective

Old English fealdan, to fold — past-participle of fold. As a color modifier, folded implies a clear-and-creased-and-arranged quality where the hue carries the visual register of carefully-folded-and-neatly-arranged textile surface. Sits at the crisp-and-finished end of the grid, parallel to pressed and trim in usage.

Niloo
noun

The Persian word for indigo plant — borrowed from Sanskrit nīla (dark blue). Niloo names the plant Indigofera tinctoria in Persian and the saturated deep blue dye it produces. The color refers to a freshly niloo-dyed Persian carpet: a saturated, slightly cool deep blue with the matte finish of plant-and-mordant dye.
