How to change wire color to object's display color?

I have a Rhino file where I am instancing a simple block many times. Each block instance has its Display Color set to a custom color.

When I view everything in Wireframe mode, everything is shown in the Layer color and not the object color and I don’t understand why.

The Wireframe settings are unchanged:

The Geometry inside the block is just a Sphere and has its Display Color set to “By Parent”:

Shouldn’t the wires now all display in their custom color in the file with all the block instances?

Weirdly the Control Polygon is also set to Object Color and sometimes you can get it to show when resizing all block instances and then it shows the correct custom colors for each.

Is there something I am missing?

This is in Rhino 8.23.25251

Already found the mistake. When we embed the original sphere.3dm the display color is changed back to By Layer. If I open the Block panel I can see it is set to By Layer and embedded.

I will check our Export and make sure it is set correctly during writing of the .3dm file with the block instances.

please mark topic as solved…
