I believe that the brown, pink, and white colors for her eyes may be natural colors that change naturally for... whatever reason, maybe in relation to how she's using her Semblance or Aura or something, similarly to how Yang's eyes turn red naturally.

The natural colors of her eyes would not affect the colors of her blushing because the colors are caused by entirely different things. A blush is red because of the blood in your cheeks. Your eye color is determined by the color of the muscles making up your iris. Though, apparently, in all reality, everyone's eyes are blue underneath, but some people have certain proteins in or on their irises that cause them to have colors other than blue. At least, that's my understanding of the fact that people figured out how to inject something into someone's eyes to strip away that protein and turn their eyes blue. By the way, that procedure is irreversable.

So, from an anatomy and physiology stance, Neo's natural eye color changes could be due to protein changes in her irises. But again, proteins are not what affects the color of your blood, nor the color of your blush. Your blood is red because of the red blood cells.
