Can African Americans blush?

Yes they can. Just because 你 didn't see it that doesn't mean 你 can't feel it.

Yes, they can . Blushing is capillaries in your face allowing 更多 blood flow. It, however, often does not 显示 due to contrast issues with skin color. In not so black people 你 can see that it has a lesser effect, and jet black people it is almost not noticeable.In general, african american (or african , for that matter), when undergoing embarrasing 或者 other emotional situations, suffer dilatation of the vessels of the face (just as caucasians and asians do), and they blush , of course, only that we dont generally notice the blushing because it is masked 由 the cells that contain the normal pigment(melatonin) in the deep layers of the epidermis.
Yes, they do blush , like anyone else..

Yeah, I've seen myself blush before.

I also have light-ish skin so it's easier to see, whereas it would be harder to spot on someone with darker skin. But in general, yeah, 你 can pretty much see any human's blush if 你 look hard enough, no matter the colour of their skin.

They probably can but it may be hard to see....

Wow, That's actually a very good question, never thought of it before! xD

Woah, dude, I think that's a little bit rude. African Americans are human too, meaning they feel everything any other person of any other race can feel.

I'm pretty sure they can,you just don't see it. They can feel it though. Any human can blush,not all of them will 显示 that they are blushing. But,this is quite an interesting question. It makes 你 think a bit.

Excuse me yes we can

Yes, it's probably just harder to see with a darker skin color. But yes they still can.
