It's not makeup or paint that makes Paul Karason's skin a deep purple colour.
The 57-year-old started making the transition from fair skin and freckles to what he looks like today 14 years ago.
"The change was so gradual that I didn't perceive it and for people around me, likewise," Karason said. "It was just so gradual that no one really noticed. It wasn't until a friend that I hadn't seen in several months came by my parents' place to see me and he asked me 'what did you do?'"
What Karason did was use a substance called colloidal silver, which is made by extracting silver from metal. It goes into water with an electrical current and then you drink it. Colloidal silver is billed as something that will cure just about everything that ails you and Karason swears by it.
Karason does not believe drinking the potion is what caused his discoloration. He believes it happened because he rubbed it on his face to treat a skin problem. A medical condition called Argyria has been linked to such discoloration since the days when silver solutions were used as antibiotics.
Karason moved to Madera, California about six months ago after living in Oregon. He said too many people in Oregon were unkind to him and he hopes Californians will be different. "I hope that they just accept me," he said. "And I think that will happen here. Where I was, I rather doubt it would have. This is a different kind of community here."
