All the DE I've ever used was white.
... okay

I´ve never seen it black. It´s always white in my experience.diatomaceous earth is black and jagged, it looks a lot like the stuff you'd use for a sandblaster.
Snail Killer, comes in pellet form, green in colour and kills slugs too. You can also get pet friendly varieties cos the original one may kill a dog if ingested. Very effective. This in Oz though.
A band of vaseline smeared around a container also works. I think it probably prevents them laying down their slime effectively so they can't cross over it.
