salam sister,
i live in paris and here they are muslim from different origins from north africa , africa , asia , and also many reverts so we have a lots of multiracial mariage and thats work mashaAllah very well, i think that what the people should take into account is more the religious aspect cause if the man or the woman who are going to marry have a good knowledge and fear of Allah he or she will treat their companions good , Allah have legislated all the rights between the man and his wife and vice versa,for the food and so on you can always find a solution heheheh,
your brother in islam,
