Race still provides a major financial benefit. Its what - 30%+ of the US population thats not caucasion / very light not white skin? And thats before you look at the international market.

While white is going to be the priority you don't want to fall behind competitors on film that does better accross the board. Not only do you lose the dark skin market but also potentially professionals like school/wedding/corporate photographers who need to photo everyone and don't want to faff around with different films for different photos.
