It's pretty obviously a spotlight. That's what the Facebook poll advertised.

If you should happen to get a gold or rainbow, you have a higher chance to get Toad Lily, Orchid Wydler, or Sakura. But don't get your hopes up, because the bronze rate is still high, and if my rolls on the other limited gacha was of any indication, the spotlight is a lie.

10+ silvers before I got a Lilac, and my one gold roll wasn't Camellia, but Toad Lily. Though I'm completely fine with the latter, at least.
