Why do some axanthics brown out and some stay gray?

[highqualityballz]

Im really like the axanthic gene, tsk line to be exact but i noticed some stay the gray/silver and some brown out and kinda look like normals. Why is that?

I think it's the same reason why some pastels get really brown and some stay yellow.

Some lines are better than others best lines is VPI

Axanthic lines are not compatible
