Depends, phenotypically. For instance, Stan Mcquay is half white and and half Japanese, yet he "looks" phenotypically Asian. Michio Grubbs, a bodybuilder from the 90s, is half Asian and half white, yet he looks like Erroll Flynn (a white actor from the early half of the 20th century.)
See, because you are Jamaican, you possibly have more African in you, whereas with a lot of black people in the Americas, they are mixed, to varying degrees. Phil Heath got those light eyes from somewhere. Donnie Simpson, his green eyes came from somewhere, right? Eric Sermon, from EPMD, aka the Green Eyed Bandit---same deal.
plus stan at least for himself embraces his Asian side moreso than irish I believe,,don't remember seeing pics of him twirling a shamrock in his hand..
