Red, unless you cut yourself and leave it to dry and then it'll turn black. Once I was picking it off myself in class and my teacher thought it was paint.

So it's black?

If you're black, it's brown
Anything else and it's white.

It's never red inside, the blue is just light reflecting weird off your skin

No, but I'm guessing you are.

blood is always red. the blue hue to your veins has to do with how your skin reflects light. blood is never blue. it does turn brown/orange when it dries due to the iron in your blood oxidizing.

If your blood is black, sure

Blood is red when the cell is alive as most of our blood is composed of iron. After it leaves the inside of the body and is contaminated, blood begins to rot and decay turning darker colors which looks black in some cases.
It merely looks black but is still either a dark red or even dark brown.
