Seeing as Zebede doesn't have the two-eye-color-thing going for them, is it safe to say that maybe the that is exclusive to psions, with different colors meaning different things? Like maybe certain combos of eye colors mix to create different psionic effects?

Yeah, the eye thing are tied to Psionics, I have no idea if different colors mean things or if it’s just like. Aesthetic.

Or in Cirava’s case, A e s t h e t i c.
