What color is Farrow and Ball Smelt Black?
Farrow and Ball Smelt Black G18 is a deep, even charcoal-grey with a neutral cast, based on its balanced #3c3c3c color value. It reads as a soft black in bright rooms, while lower light brings out its full, shadowy depth. Use it on cabinetry, interior doors, or a single wall where a solid dark contrast is wanted without the absolute sharpness of black. Pale plaster, crisp white trim, light oak, and brushed steel give this shade a clean, grounded setting. On an exterior detail such as a front door or window frame, Smelt Black can create a defined outline against lighter masonry or siding.

What are Farrow and Ball Smelt Black undertones?
Smelt Black reads as a deep, low-saturation charcoal that sits very close to neutral rather than clearly blue, brown, or green. In the supplied digital sample, the color has no strong measurable undertone direction, so any subtle bias may depend on the actual paint finish and surrounding colors. Farrow & Ball describes it as a “soft base metal” paint color, which fits its visibly muted, industrial-style dark gray character rather than changing its main charcoal family. Warm artificial light may make it appear a little softer or less stark, while cool daylight can emphasize its neutral gray quality.
