Do you have pictures of her room, windows, doors, etc? The Bedding is adorable. White walls (like in the PB photo in room) might be pretty. Or, does she like pink or blue? BM First Light and Windmill Wings are BM 2020 Color of the Year which might be PERFECT! .https://www.benjaminmoore.com/en-us/color-overview/color-palettes/color-of-the-year-trends-2020

so we have this, on furniture

this on bedding?

I would forgo the sea salt (which is the wrong tone for this combo) and try something like this.

(BTW, to get a true representation, you need to prime that wall white before trying the samples. that darker gold tone will alter that one sample coat)

BM colors:

you could also go w/a very soft, lighter blush color.
