Can African Americans blush?

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

Yes, they can . Blushing is capillaries in your face allowing আরো blood flow. It, however, often does not প্রদর্শনী due to contrast issues with skin color. In not so black people আপনি 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 অথবা 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 দ্বারা 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, আপনি can pretty much see any human's blush if আপনি 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 প্রদর্শনী that they are blushing. But,this is quite an interesting question. It makes আপনি 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.
