I now agree that we should not mix aliases with physical colour parts any more than we should mix them with "core" parts, that's why I'd like to reach a conclusion on the title prefix to be used for Aliases.
Parts may have mutliple aliases, due to a combination of the opaque/transparent mould phenomenon, LEGO part numbering evolution and our desire to group patterned parts with their pain version using pNN suffices. In the case of 3626bp82 (which is what prompted this discussion), 50003.dat would be an alias. The 7-digit element ID (if/when we know it) would be a Physical Colour file. There are many examples of more than one 7-digit number for the same colour, possible indicating the LEGO has just as much trouble understanding their colour palette then as we do.
