I’m not sure that it is widely recognized, but is sometimes referred to as racial identity disorder, or ethnic identity disorder. Although it is not the reason behind all cases, a common behavior that you may have heard of is when someone with darker skin attempts to bleach their skin to appear whiter. I don’t really know much more than that, so hopefully someone else will be able to expand on what I do know. I just don’t think that it is a widely accepted concept at this point in time. I’m trying to find an article for you, but I don’t see anything worth reading. I’d wait to see other responses before taking my word for it. I’m just going on what little I’ve heard.
