Hmnn alright, this is pretty interesting it seems to be that O X Delta symbol thing, where the flower color bed you are in results in "common flower color flabebe of that flower color" and the other colors can just randomly appear in there as well
White, yellow, and orange can be found in yellow flowers Red in red flowers Blue and white in purple flowers
White can probably be found in any color patch...not sure if there's a purple, but Flabebe can't be bred with each other (all female species)
Ah ok, good info, it seems purple is just the special color findable anywhere(or maybe in purple flower patches particularly?).
Route 4 you can find: White, Yellow, Orange in yellow flowers, Red in Red flowers During the day. Confirmed. Someone mentioned finding Blue Flabebe at night in (Route 4?) in another thread as well though it is unknown if they meant route 4 as they did not confirm location. Route 6 you can find: Purple, Blue in (unknown) flowers at (unknown) time of day. Confirmed.
EDIT: It is unknown at the moment if the confirmed purple reports are actually purple flabebes or some sort of pink /confusion for red/orange at night from partially colorblind users or not(aka no screen shots yet).
