Canonically, the Exile had brown hair, brown eyes (iirc) a cyan lightsaber and was light-side aligned. Also she was a girl.
Also, when Jedi construct their lightsaber each one is unique to them due to the parts that they find themselves upon, so sometimes someone may end up with a different colour.
Either way, George Lucas admits to allowing EU-canon into his canon. He always searches around and allows it into Star Wars (Aayla Secura, General Grievous etc.) and you gotta remember that this IS 3,500 years BBY. Things that happen now might not be the same in 3,470 years time. Times change, like when they stopped using Force-imbued weapons and started using lightsabers instead.
