The confetti I sunfaded took several months to fade anything away, even when it was really sunny >~< She does look like it might be sunburned? But I cant tell for sure. But I would also be careful and check her every day if you decide to sunfade her more, Confetti is a pony very prone to sunburning! (I have seen many really badly burnt ones and I had to stop fading mine because she showed early signs of sunburn) I wish you luck with her!
