From what I understand a mojave x lesser or lesser x lesser will give you a pure white BEL. It is the mojove x mojave pairing that will give you a bit of an ivory or a "dirty" BEL.
I have researched this a litte bit, and that is the conclusion that I have come up with. Someone else chime in if I am wrong, but I think you can get a white BEL. That is why my next purchase will be a lesser!
