User blog comment:Maki Kuronami/Lesson 24: Why the Naming Rule of Remnant Exists/@comment-25436196-20140926023017/@comment-10380701-20140926023440

A rule actually making sense in a constructed world is very rare. I've seen some fictional planets and sometimes they fuck up their own rule.

Remnant's naming rule, is just a trend, but it's a semi hard-on rule because it's a part of their history now. There may be some non-color names here and there, but most people are likely color themed.
