I have pale looking blue velvet that developed into what looks sorta like a golden bee. The white is very solid but theres a hint of blue on it. It came out looking yellow tinted in one image, and blue tinted in other.
Snowballs are neo palmata, blue velvets are neo davidi.
I'd love it if you could get some more in focus pics. The white neo has long been the missing holy grail.
Most often when someone has white it is usually bacterial or high gh thickening the shell. Since BV don't rely on surface pigmentation, but rather internal blue tissue color- perhaps this is your answer.
Maybe you have something. I hope. Time will tell. I'd be very interested to see how this turns out. How old is yours?
I have a near white cherry as well that I am waiting to age before doing anything with. However mine is caused by some kind of mutation with shell pigment. I don't know if mine is male or fem yet, but the nice thing about yours is that she's a fem. In cherries often the color is carried on by the fem.
