Hello! If you are referring to the mercury substance, mercury is a bright red color, usually used in early thermometers and is deadly if humans have a lot of constant with this substance
Mercury as in the element, or the planet? Well, i'll tell you both, just in case. The planet is a dark grey, and the element is kind-of a silvery-white color. Hope this helps! Stay smart, ~{Dunsforhands}
