Homemade Ardoise

#1d043a
Notes

Homemade Ardoise (#1D043A) is a deep indigo 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 (268°, 87%, 12%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Homemade

Sits at the neutral-and-traditional end of the grid, parallel to handmade and handcrafted in usage.

Ardoise

Ardoise color refers to a Château de Chambord ardoise d'Anjou roof-tile face in raking sun: a dark blue-gray with the matte finish of metamorphic Carboniferous slate-shale on a hand-quarried 16th-century roofing tile.
