seems pretty normal, i am mixed aswell and i like white, mixed (brown), japanese (but not thai, vietnam and so on, but i like indian women for example, but not pakistani or afghan. and so on, but i've never seen a full black girl that i really was like "wow she's so hot". Don't know if this exists, if it does it's really rare obvioulsy ^^. but there are some fine mixed girls i've seen holy shit, really often i really prefer them over most white girls aswell, they look healthy and not so overly pale, but it depends, some girls look really nice being pale some look nice tanned. so to come to the conclusion, it's obviosly not a racist thing. but i've seen men actually looking for full black girls which they like, so whatever, everyone should pick what they like.
