Yes I played X, but nowhere did it say (as far as I can remember) that all Al-Bheds eyes are a certain color, and all Non-Al-Bheds eyes are a different color. Or it did not say that one eye is different because she's al-bhed.

I didn't notice that either, and if it's because she's half al-bhed, wouldn't Cid's eyes be blue or gree? From what I recall, they are brown...(unless I'm totally mistaken)
