Thomas, please excuse my tardiness at replying to your very interesting posting. Yes I agree with you about the time gap between Livadia and the interiors at the AP. Though I think we can use the gap between moving in to the AP in 1895 and the new schemes by AF and with help from her brother G.D. Ernie in 1903 as proof of an emerging personal style!
I see the rooms at Livadia as the maturing of her taste and as women. I love her rooms at Livadia. I also have a real fondness for the clutter and whiteness of the Mauve Boudoir, in the whiteness I mean, the Hepplewhite style furniture is used as a foil to the over powering mauveness of the scheme. I think AF had a real eye, also the early rooms sometimes seem to lack confidence, coming from a rural German court, suddenly the purse was always open. \if you see what I mean.
Hope this is not too confusing, would love to know what you think.
I too would have loved to see the wallpaper from the Mauve Boudoir, they say it shimmered in the right light.
