Kakashi's Sharingan is his left eye, which was a gift from Uchiha Obito. Usually, it gives him special powers, but at the expense of draining his life force if he keeps it open, so he usually shuts it or it tires him out because it is in a "constantly active" state. (It's red with three black tomoe.) While I understand the powers will be inactive, will the eye still be red with the three black tomoe? If so, will it be a drain at all on his life force if he keeps it open at all times?
