Well, I dont know for sure, this is a guess. But "red" often represents " anger" 또는 " evil", being mad. 당신 heard of a mood ring well when your mad it usually turns red I believe. " Green" on the mood ring symbolizes being calm. And well 당신 know the Jedi they tend to focus towards that mind set. And Blue is similar it means " normal/fine". But if 당신 think about it alot of things that are evil are represented 의해 the color red. The Devil for instance is said to be red 또는 has been depicted that way. Hope I gave 당신 an Idea at least.
Want to know something cool. off topic but Vader in German means father. Thats how Germans say father is " Vader". Ironic that he Became Darth Vader just as his wife gave birth to his twins.
