Just GAG search black and white and you'll see millions of questions asked by black girls on here about whether white guys find them attractive or not. And how they find them really attractive. Being white, your chances with black girls should be pretty good.
I'm a mixed race girl and I love "white" guys! Probably sounds really bad haha but yeah over here, a lot of the mixed girls actually date "white" guys most of the time and yeah hopefully that answers your question because a lot of mixed and colour girls are into them :-)
Some do, some don't. You would be amazed at how many black girls would admit they liked you if they knew you were interested
