Of course inks come in colours other than green; pick a colour, any colour and you can probably get it.
So you ask if tattoos come in colours other than green, then ask about black tattoos? ...Yeah. Pain is totally subjective, it depends on your tolerances, but I've heard it definitely isn't the least painful place to get one. I've seen truckers pass out from a tattoo on their shoulder, but a college girl not even bat an eye at their wrist getting done, so yeah, you'll find out how much it hurts if/when you get it.
Why would you blood turn a different colour? What the hell?
You can get tattoos in any colour, and it hurts more on sensitive parts of the skin, like the wrist, upper inner arm, ankle,foot etc. And it mostly depends on your pain threshold whether it works or not. Also your blood won't change colour lol xD
Tattoos come in pretty much any color its ink injected into ur skin. Different colored tattoos dont hurt any different. The wrist is a painful spot theres a lot of bone.
Blood doesnt change color its the ink thats colored. Go on youtube and watch a video of someone getting tattooed
