How does anyone here make it so that the two versions are different in Kodi listings?

1. Scrape both movies into the library
   
2. Hightlight one movie and call up the Context Menu... https://kodi.wiki/view/Basic_controls#Context_Menu
   
3. Select Manage
   
4. Select Edit Title
   
5. Rename movie to something like... Its a Wonderful Live (B&W)
   

---Edit---
In the above I have assumed it is the same movie but a different version.

If it is two different movies, then you should always have the year in the name of the movie file. They will both scrape ok. Then you can still follow the same procedure above to distinguish between the movies in the Kodi listing.

Yes it is the same movie, just a 'colourised' version

Ah right. So it is the old 1946 version, that is B&W and later colorized.

Thanks @FXB78
