Her eyes definitely aren't evidence of being a fauna or half fauna, considering that most of the characters don't have normal eye colors in the first place. I mean, Yang's are frickin lilac, Ren's are bright pink, Pyrrha's and Glynda's are bright neon green. Even when they have a normal eye color, it's an unnatural shade, like Jaune's being dark vivid sapphire blue.

So yeah, I agree that Blake's eye color isn't evidence of her being a fauna.
