He's in Romania, they probably use different additives there that turn the plugs a different color. Bromine used in Super Unleaded turns plugs red, it's not a big deal.
When you were told to check voltage, it wasn't alternator voltage, it was voltage AT the fuel pump. Check the wiring going into the fuel pump harness to make sure it's receiving 12+ volts and not 11.xx volts at idle.
