I think you're confusing the two bels. There's blue eyed lucys and black eyed lucys.
Fires are part of the black eyed group.
Mojave lesser and Russo are examples from the blue eyed group.
Both bel groups create all white snakes but black eyed lucies often have yellow spots. And crossing members of the two groups won't result in all white.
Fire to vanilla gives you vanilla creams and vanilla to vanilla gives you super vanillas. I believe if I remember correctly a vanilla cream will act as a super in that you will not produce normals.
