Espada-Shinigami

Alright, as a little introductory, this rant of mine is pretty much about why each of the coloured Links have such odd personalities that don’t seem to match with their specific colour.  The purpose of this is to provide a little insight (and research for those who are lazy like me) and explanation.
First off, I'd like to begin with Red. There has been a lot of speculation and disagreement with Red's colour.  Everyone I know who has played Four Swords and never read the manga have always associated Red with an angry personality because that is what his colour most commonly represents, and for some of those who have read the manga, they sometimes dislike and disagree with Red's sweet, innocent, and optimistic personality.  Not only is this due to the angry colour, but also one of his main weapons: the Fire Rod.  Fire, as well as the colour red, represents anger or fury.  However, the opposite of anger is also connected to the colour red.
