Her eye became pink, not light purple. Yang's eyes are light purple. Neo's eyes change between brown, pink, and white, to correspond with her neapolitan ice cream (chocolate, strawberry, vanilla) color theme.

To be honest, you have a really, really interesting theory. Though, her eyes being white likely isn't her perspective. In Painting the Town, when she was standing next to Roman in front of the mech after his speech, both of her eyes were brown. It seems that her default "not in the middle of a fight" eye color is brown.

During fights, her eyes tend to change to where one is brown and one is pink. There's also the confusing fact that which eye is which color switches. Sometimes pink is on the same side as her pink hair, sometimes it's on the same side as her brown hair.

When she went to stab Yang after knocking her out, one eye was brown, the other was white. (For some reason, it won't let me add the screenshot, so )

When Raven showed up, landed a hit on her that sent her flying back, and scared the crap out of her, both of her eyes turned white.

It's really hard to tell exactly what the color changes mean at this point, but they really might have something to do with her Semblance, like you're suggesting.
