Paul Karason was not a member of the Blue Man Group, but probably could have toured with them. Karason became famous when his skin turned a shocking hue of blue, after using colloidal silver to treat a skin disorder! He believed the blue color was slowly beginning to fade when other serious health problems arose. Lately, he faced a heart attack, stroke and pneumonia that ended his life at 62. Asked if he had any regrets, Karason said he never would have used colloidal silver if he knew about the awful side effects.
