Is it possible to create/market green-colored salt?

As everyone knows (who has ever seen salt under a microscope), it is a clear crystalline substance and is not “white,” as some folks erroneously claim.

But, could a green color be added to it, so that it could more easily be seen, when you are sprinkling it on your eggs at breakfast?

The reason I ask this, is because sometimes, not being able to tell how much salt I’ve already sprinkled on my food, I once in awhile over-salt something, and with my high blood pressure “issues,” that’s really ill-advised.

The reason I suggested the color green, is because paprika is already red, and pepper is already black or brown (and I guess a green variety also exists, but I have never seen it), so green seemed like a possibility, for those of us who wish to know how much of that spice we are putting on our various foods.
