I have two objects and want to subtract one from the other. I typically have each object its own color to keep track of what things are for. The annoyance I have is after the subtractions the object that has been subtracted from becomes the color of the object I was using to subtract.

`I guess the easiest/intuitive way I can think of is the new face after subtraction should inherit the color of the body it becomes a part of instead of the part it came from.`

It would be really great if the object that was subtracted from could keep its color instead of inheriting the color of the removal part.

Here is an example. I have this bi-stable compliant system I am working on. I use the blue-ish color to indicated flexible material (TPU S95) and the white to indicate rigid material (PETG). After I subtract the blue flexible area from the rigid, the rigid part is now blue instead of white at the intersecting points.

I am sure this is a low priority issue but if it is an easy fix it would be great.
