[SPOILER FOR GO! PRINCESS PRECURE ABOVE & below]
I think it has always been different with Pink cures. Heck, even Mana’s hair turns bright yellow even when she’s pink in civilian form. I don’t think the same happens with the others? Brown shares the same palette as yellow, so it’s kind of natural that they end up with yellow hair. And well, all others have some kind of lightening in tone, so I thought that was normal.
SPOILER: And, well, I was just sort of thinking out loud on my own basing myself on stuff shown in the actual series and I really wasn’t asking for spoilers? If I really wanted I could have found out on my own? Please, don’t do that again! Hey, I’d be very happy to be proven wrong (because I still think it is possible for Yui to be a Cure, I didn’t mean to say that I thought it impossible?), I never said otherwise.
I was just saying my opinion at the moment. I don’t think it hurt anyone, especially since I clearly support Yui becoming a Cure, and will always support any evidence of it. But really, you yourself labelled your second argument as “spoiler”, and I obviously did not know because it was made clear in my post that I had no clue. Next time, please don’t go throwing around spoilers, especially if you know that they are spoilers to the person you are talking to.
