Probably, since they seem to be taking that path. Go princess is taking a pretty similar path to Fresh surprisingly, so I would assume Twight might be Red, or the usual Purple.
There are alot, alot of purples in Precure recently. They really do need their own color category now.
Maybe princess twilight is cure scarlet but to soon think about it now.
Holy crap you were spot on.
Latest episode shows that Twilight becomes Cure Scarlet.
Although it seems out of place since she becomes a color rather a concept unlike the rest of the girls. Flora, Mermaid, Twinkle and Scarlet? Might be better if she just stayed Twilight.
