Ummm regardless if its a work of fiction physics still apply to some degree. Of course Kishi gets to cheat a bit, chakra helps.

1. Amaterasu is the ONLY fire in the series that is black. That's why this conversation exists. Pakura's Scorch Release is white in the center so things in the Naruto Universe get whiter as they get hotter. Making the fact that Amaterasu is black even more peculiar. it burns for up to 7 days and 7 nights.

2. If you need fuel. Chakra, or whatever it touches acts as fuel, another property unique to Amaterasu.

Darui has black lightning. So that is what we will say. The only thing that sets it apart from regular lightining release is that it is black. It behaves in the same way as other Lightning attacks
