This article continues coverage of Superman costumes and costume components offered for sale publicly in the marketplace attributed to use in the Superman films of the 70s-80s starring Christopher Reeve and characterized as “original” and “authentic”. As part of the ongoing analysis, and in buidling tools to assist with authenticating costumes currently in the marketplace, I thought it would be productive to analyze the colors of the costume, and establish benchmarks using confirmed authentic costumes as reference.
