EVE General Discussion

The Amarr are the regal, holy race. gold is traditionally associated with the wealthy, of which the amarrian church (and by extension their military and government) pride themselves on thoroughly.

grey is the color of emotionless, cold, calculating steel machines. the caldari are a corporate dictatorship, you are born into a megacorporation, your role in the ever moving corporate machine is decided before birth, there is no room for choice, compassion, or ethics.

red/brown is the color of rust. the minmatar, trying to pull themselves from the wreckage left behind after amarrian enslavement, natrall would use whatever they can find, maintenence for such a society is kept to "only the necessities" as they dont have resources to spare, so as long as a ship flies, its in working order. polishing off the rust is a luxury they just dont have the time or man-hours for.

green is commonly associated with life and the organic, something the freedom-democracy-'murica style gallente take pride in. most of their ships and stations being themed with organic (and often quite phallic, you sily space-frenchies) symbolism.
