According to Ralph Davis the cleanest lucy's are created by breeding Platty to Lesser if you havent been to his site already I'd highly recommend checking it out. He has write-ups on many differnt morphs.
just don't use mojave and you'll get a clean white snake
Actually Mojave X Mocha makes a REALLY white BEL and same with Lesser X Mojave we hatched out 3 Lesser X Mojave Bels this year and they are PURE white!
I stand corrected. I thought an all white snake was a bel (regardless on eye color).
bel = Blue Eye'd Leucistic
Leucistic means lacking all pigment in the skin. which alot of snakes we call leucistic arn't true leucistics such as the super mojave because they do have pigment in the skin... so yea. theres also super fires which are black eye'd leucistics, but most of them have yellow spots which also makes them not true leucistics lol. i guess in the snake world "close enough" is good enough to call them leucistic.
Lesser/Butter x Lesser/Butter = Clean
Lesser/Butter x Phantom/Mystic = Clean
Lesser/Butter x Russo Het = Clean
Russo Het x Russo Het = Clean
Anything with Mojave = Not pure white
I donno if a Russo Het x Phantom/Mystic has been done...

The pics you posted looked pretty yellowed out to me.
