Dying your fuel tank?

I am trying to black out my Savage. I was going to remove the chrome from the wheels. and I got this crazy idea of dying my gas tank. Using standard RIT dye. Your thoughts? As to what this could do to the visibility of the fuel (would depend on how long it was in there). Would I dye the inside AND out? Would the dye get into the fuel, what could this do to the engine?

p.s. anyone know if the stock Savage tires are white or black plastic? If they turn out white, I don't really want to boil the tire off to dye them...
