Love, love, love the really pink one with the spotty mat and daisy wall decos.
It's colourful but not too full on and you could pick up a number of those shades in the quilt - the lovely sage green would be a lovely highlight colour.
I was going to suggest a coloured rug for the middle of your floor, something to break up the big white wall - a gorgeous handmade quilt or something, or something hanging from the ceiling to add some colour.....or perhaps a dado rail around the base of the wall with a different colour. That lovely sage green as a feature colour at the base of the wall would be nice.

Mostly just thinking outloud there, don't know if it's much help!
