But the red as passion is a lie - it's not really coming from the people at all, because they weren't like that. As the emperor says, none of them were as narrow-minded and superficial as that version of the tale suggested. The emotions portrayed in it weren't real.

The blue - yeah, I can see where you're coming from there, because the emperor is very much like the version of events that he recounts, but that isn't true for Nameless. Revenge is why he's there, but he tempers it at the last, and proves himself different from the tale he invented, so there's a clash there between the story and who he is.
