It's kind of cool. I think a Spice Girl used it for her daughter quite some time ago (10 years +).
It comes with nice nicknames, you can use
Belle or Blue or
Bella.
The flower is nice.
I think it will get used more but it won't get super popular because:
1) the belle/bel/bell/bella - phase is almost over
2) Blue even feels slightly dated because so many celebs used it some time ago
3) many people told me they think of cows (I don't)
