I agree with Chris. Bear in mind that the source of the luminous phenomena we see when we see a meteor, is not so much the meteoroid itself burning up: it's the atmosphere around it becoming incandescend.

There are only a limited number of meteor spectra, so the colors aren't real well understood, but I'd be surprised if you saw the nickel emission over the atmospheric oxygen. The majority of slow, bright meteors are reported as green by many witnesses, but only a small fraction of those contain significant nickel.
