eli5: Do people actually visibly turn pale (ex. when they realize something awful, when they’re scared, etc)?

Question

I’m not sure if “turning white/pale” is an exaggeration or if people actually do turn pale in certain situations. I’ve never witnessed it myself, anyone here who has?

Not sure about fear but I can tell you that every time I’m sea sick, someone tells me I look literally green like a cartoon.
