Darker pigments hook more in oil, if you look at every oiler made the last 10 years it is hard to find a lighter color ball that covers medium-heavy on up.
The viscious particle comes to my mind as one of the last super strong light colored bowling balls. The NV is also a very light colored ball for such a strong cover but overall that is why they all use dark pigments like purple and black.
