Came here to say the same thing, for years I was believing my blood was blue before it hit oxygen....
I was going to add the "hitting oxygen" is an important part of the blue blood myth back then.
Which is really funny since your blood is already oxeygenated
Ah, but I think the "blue" blood you see is in your veins, which carry "spent" blood with low oxygen content. Those kinds of little truths are what make myths believable, too.
