Someone in the fleet suggested that a black band be painted on the leading edge of the slats so that ice can be more easily seen from the cockpit. I guess it was a good idea in theory but unfortunately the black paint quickly wore away as it was on the leading edge of the wing, leaving a silver "stripe" exposed on the black band. Guess what that silver stripe looks like from the cockpit, especially at night? Well, like I said, it was a good idea in theory...
