Black salt is not black, but a little pink in pearl ash. Indian black salt is rich in trace elements such as sulfide and iron, and has a strong sulfuric acid taste. The black lava salt produced in Hawaii is dark in color and contains a small amount of activated carbon and volcanic rocks.
The color of gray salt comes from the trace elements it contains or the clay it comes from. "French grey salt" is produced in coastal cities of France, and it is an unfinished wet grey salt. Smoked salt is also gray, which is a new product in high-quality salt. This salt is smoked on charcoal, so the food cooked with it often smells of smoke.
