Eli5: What gives Himalayan pink salt or black salt or any other natural colored salts their color?

Question

I am aware many minerals are there in the salts and they may or may not have health benefits or flavors but what gives these salts their color is it a particular mix of other mineral salts or any particular element

Answer 1

In pink salt, it is other minerals. I have seen the mineral spectrum list years ago, there are around two dozen other elements in the salt, some of which give it the color.
