Very interesting idea. So if I understand it can take abuse, pieces could be ground right off and you would have a different texture but the color would remain, unlike basically anything else where it would revert to the base material color.
I’m not quite sure what you have in mind but it’s not really abusable, it just won’t deteriorate as quickly as other types of painting.
If you cut into it then you may or may not get different colors depending on where you slice. In that sense it’s not much different mechanically than oils, just with way more depth.
