Inside your veins your blood is blue. When it oxidizes with oxygen it turns red. When it comes out in large volume, it looks very dark, almost black like.
Your blood is actually never blue inside your body although it is a lighter or darker red color depending on oxygenation level. That coupled with natural color variation probably explains this picture.
I used to think the same about blood being blue, give it a quick search and you’ll see it’s pretty much unanimous that your blood is never actually blue
You can color me skeptical on this one. I’m gonna go on record and say that I don’t think the vaccine turns your blood black lol
