You can see the original commit history in forks of nanocolor that occurred before Andrey Sitnik rebased:

* https://github.com/antonk52/nanocolors/commits/main

* https://github.com/corysimmons/nanocolors/commits/main?after...

You can, indeed, see that they lack all of the original repo's commits.

In addition to what others have pointed out:

The commits in nanocolor's git history also don't include Jorge's verified signature, which would come with the fork.
