Clear Chimney

#150318
Notes

Clear Chimney (#150318) is a deep violet 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 (291°, 78%, 5%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Clear
adjective

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

Chimney
noun

Old English chimene, cooking pot via Latin caminus, furnace — the deep-soot-black interior of Northern European stone hearths, where the bone-black and lampblack sediment accumulates over generations. Chimney color refers to a freshly soot-coated Brontë-period Yorkshire-cottage chimney-throat in raking light: a saturated, slightly cool deep black with the matte finish of multi-decade soot-and-creosote sediment on hand-cut millstone hearthstone.
