1) Sasuke didn't get the black balls because he wasn't using the Tailed Beasts.

2) 6 Paths Sage Mode and the cloak Naruto got are two seperate but related things. Having 6 Paths Sage Mode seems like a prerequisite to Utilizing the cloak and by extension the Truth Seeker Balls.

3) Sasukes black Chidori in CS2 was likely a result of the chakra not being his/Orochimarus evil chakra. Also, it turned everything black/dark, that was a a result of the curse mark more than natural/sage energy, because Sage mode has had that effect on no other technique

4) Darui has special colored lightning, but thats about it and that is confirmed to be just lightning.
