> But this does also fall a little into the LEGO trap of claiming that ‘the yellow doesn’t specify any specific race so it can represent any of them!’ Which maybe held water right up until they wanted to make a Lando Calrissian minifigure and it became extremely obvious that he couldn’t be yellow […]

If there was only one colour available, and everyone knew there was only one option, would that lead people to think it was more neutral? Did the introduction of variations also introduce the idea of non-neutrality (of yellow)?
