Hi Greg F., longtime fan here. I had no idea this sort of forum existed and your answers have made my day.
However, one thing has bothered me about the Mask of Life for a while. I remember reading somewhere (perhaps in a book or on the website at some point?) that the Kanohi Ignika was originally gold, but that it would turn silver and eventually black (possibly as Mata Nui died?). We saw the Ignika turn silver at some point before Toa Ignika formed, but were there any plans for the mask to turn black? Otherwise why was this detail even written?
