Red. They're mostly human, but even if not: the Blood-Wars (and the terrain on Avernus) have well established that most fiendish blood is red too. But feel free to improvise: it's fantasy after all. Not sure why this would be a dispute between a player and DM.
What colour is tiefling blood?
It's not "blood" it's a liquid fire that "dries" as a scorch mark. That's Metal 🤘

I would agree that it defaults to red unless established earlier that it is different for homebrew/personalized reasons.
Whatever color it is, remember, cold water to get it out of clothing.
Thanks man😂
