Paint colors are going to look different in different spaces. I wanted an ultra light pink for my little girl's room, and I went with BM Opal. Just be aware that pinks reflect really strongly off each other, so this color looked almost like a cream color when I swatched it but is very much pink once all the walls were done.

It seems I am always starting my replies with "from what direction do you get sun in the room? With delicate colors, sun can ruin what looked great in the can.

If it is south facing, try BM Peach cloud

If it is north facing, try BM Elephant Pink.

I do not suggest you use pink in a west facing room. See if you can sell her on a lavender instead., try BM Misty Lilac

East facing, again no pink...let me ponder and see if I can find a good pinky lavender.

BM violet pearl has some red undertone which will warm up the east light.

The room is south facing
