Why are most of the Irish in Boston orNYC not the stereotypical "pale skinned" and rather natural tan or olive?

I don't know where you get your information bro but most Irish catholic americans are not black Irish. Most are paled skin with light hair and eyes, I know this because I'm of Irish catholic ancestry and grew up in a mostly Irish catholic/Italian neighborhood in Brooklyn. You're evidence of how people still believe the negative stereotypes of Irish catholics and other ethnic whites.
