XREF layer color doesn't change

[Camryn]

I have a "base" drawing which several drawings xref to. When I change a layer color of a particular layer in the "base" drawing and when I open a second drawing that xref's this base drawing, the color for that layer does not change to the new color I selected on the base drawing. Any ideas?
