It's mostly based on diet, not breed.

That said, there is a tendency for some breeds to produce wild-type white eggs, but most commercially kept hens produce brown eggs today. You can make the white ones look blue by controlling the diet the hens have access to, so if you lower the fresh vegetable and insect component (so lower carotenoids) you get blue-ish eggs. And sick hens, but hey, they don't care.
