I've been thinking, is there a traditional significance somewhere to green equalling will, blue equalling hope,
orange equalling avarice and indigo equalling compassion?
I understand the link between pink and love, red and rage, yellow and fear and black and death, but I'm not certain of the link for the other colours.
Were green/blue/orange/indigo plucked out of the air and randomley assigned meanings or was it more deliberate than that? Does anyone know?
I'd imagine that green was picked for will purely because back in the 50s (or whenever) someone thought it would make a good costume.
