XNormal, 2 colors of normal map

Waterbear

I've tried searching for this but I must be using the wrong terms, I have this normal map. Why is one the typical "purple" color and the other is orange?

How can I change this? Does it matter?



Thanks!

Your highpoly or lowpoly faces are probably backwards for that area.

Yup, they were backwards. Thanks!
