I'd redo pigment experiments. As alcohol should dissolve everything ,
but leave only lycopene.
Start with hot wash with water. Followed by hot wash with alcohol. If
no results redo with crushed petals and filter through coffee filter.
If you have access to microscope, do epidermal peel.

I hope you find an answer. I wouldn't have thought you'd have the

alcohol, isn't it? Maybe that bloom is just more yellow than it
to be in your photo, but when things get toast colored and start
into brown tones I've always thought that was due anthocyanin being
present. Maybe Chuck will see the post.
