White roots on a mini phal

[Mere313]

I decided to repot the mini phal I purchased a couple of months ago. It was originally potted in spagnum moss and I was concerned about the center not drying out enough. I'm really glad I did. The moss was so tightly packed, there was no way the roots in the center had any room to breathe.

My concern is that some of the roots in the middle are white instead of the normal gray-green. They seem firm to the touch and not mushy. i'm thinking that because of how packed they were in the moss, there was no way for the roots to photosynthesize and produce chlorophyll which is why they're white instead of green. Are the white roots still functioning roots or should I cut them off? Thanks!
