System Information
Operating system: Linux-4.19.0-6-amd64-x86_64-with-debian-10.2 64 Bits
Graphics card: GeForce GTX 780/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 418.74

Blender Version
Broken: version: 2.83 (sub 0), branch: master, commit date: 2020-01-10 17:32, hash: 01d9a2f71b
Worked: (optional)

Short description of error
When I link a collection (instance collection) in a scene , colors of object ( object.color ) appear white.
This is the case either by switching the viewport to solid mode and use Object shading color type , or in rendered mode by using a shader that get the color with the object info node.

Some extra infos :

If I link the object it's working, it's only when they are inside a collection instance that the color is set to white.
If I get object color with python console the color is set correctly but it doesn't show up in Workbench, Eevee or Cycles.

Exact steps for others to reproduce the error
Here are two files :
bug.blend
lib.blend
One is lib.blend (the data to link into the other scene) it contains a cube that is red either in workbench set to Object shading color, or in eevee/cycles render mode.
The other one is bug.blend where the collection containing the cube is linked, Cube appear white. We can still access the right color with the python console but it doesn't follow to the render.

I found that the issue occur even if the instance is local :

This file may be simpler to debug :
bug2.blend

It's a red cube and a collection instance of the same cube, the instance is white.

I finally find why this is happening , objects inside the instance collection inherit the color of the empty instead of keeping their.
So in a way it's working correctly , in another it's a weird behavior because objects doesn't react the same way once instancied. Here it's how it looks in my scene, first image is the library file, second it's how it looks once instancied and linked in another file :

Closing since this is working as intended.

Although we could have the option to use some object attributes from the object instead of the instancing object, I don't think we would want this for every setting - need to see if this is worth supporting and for which properties.

Ok ! Objects ID are preserved which is a good thing, Object color could be quite helpful for shading, but I understand !
