3d plotting colors not matching (input data vs results)

[javoha]

Describe the bug
When using the 3d plotting routine for certain models, the color of the inputa data (surface points and orientations) does not match the colors of the respective results (surface meshes, lith block). This only happens if show_lith_block=True, and we tracked it down to only happen on Windows system, not on Linux.
It also seems to be related to models having multiple structural elements in a structural group.

To Reproduce
Run the following example on a Windows system: Example7.

Expected behavior
Colors should match respective results on all systems.

Screenshots

Additional context
@Leguark suggested that you might be able to help @banesullivan, as this seems to be at least partially pyvista related.

Edit: Annotated example.

Would you please include a import pyvista;print(pyvista.Report()) for the Linux system this is working on and the windows system this is not working on.

Further, would you please annotate the screenshots a bit more clearly to help me understand which components are not colored correctly

Hi,
thanks for taking a look at this. I annotated the image in my first post. You can also compare it to the linked example (from a linux) where the colors are correct. We ran it on multiple windows and linux systems and were able to reproduce the behavior.

Here is the report from my windows (wrong result):

Thank you! I'll try to take a look into this!
