well I'm partly Italian so I not sure if you will take my answer as valid or not but. I don't see why he wouldn't like you based on you being black, I don't think he would mind. I don't really think ethnicy matters anymore like it used to. I personally find black girls very beutiful as much as I find any other race of woman hot. he most likely does not see a problem in it and if you make it clear to him that you are interested, I'm sure he would love to go out with you. I don't know the full situation so I will help ass much as I can but maybe you should just try spending more time with him. be a little more flirtacious with him but keep it low key until you get the hint of whether he is interested or not. if you think he is then try being a little more flirty, once he knows you like him I see no reason why he wouldn't love to go out with you.
anyway good luck and take care
