There are light green patches on my forearms. They are somewhat darker on my biceps. I don't know how to post a picture but would be willing to do so. Online I read about hypo chromic anemia but I have no symptoms of it. I also read about copper being a possible cause-- as I have taken some zinc, this may be it (but I am unsure). Finally, I am not overly concerned, but it would love a doctor on here to give me some insight.
