Upon creating an assembly with linked parts, when the assembly is frozen all parts lose their original appearance configuration and display the default appearance.

This is the same issue as #1185 but it was marked as completed.
I'm not sure if the issue is still there or if it was fixed but the fix is not available on the release version from FreeCAD addons.

Looks like you are using upstream FreeCAD. Right now, the color is only preserved when you do freeze using my branch. Please try that first. The color preservation will be available once the topo naming patches got merged to upstream, likely in the next major release.
