What color is Onyx?
Onyx is a very dark, near-black color with subtle warm gray undertones, hex #353839, close to the surface of polished volcanic rock. It reads darker than charcoal but retains just enough gray to avoid a pure, flat black.
What is the meaning of the color Onyx?
Ancient Greeks and Romans carved the banded stone onyx into seals and jewelry, and the darkest variety gave its name to the color. The English word entered color use in reference to this stone, with black onyx traded across Mediterranean markets as early as the first century CE. By the 20th century, the name was adopted in the luxury goods industry to signal refinement, appearing in product lines from watchmakers and pen brands including Montblanc, whose Meisterstück Onyx edition used the name to describe its deep black finish.
