Take a look at SW Alabaster or SW Extra White.

Frost Bite is an off white, same hue family as Wool Skein, which means they relate (go togther)

could be a nice transition from the floor to the wall.

Why not just paint all the trim in Wool Skein, in a satin finish?

My first choice would be Diana's suggestion because there is not much woodwork and none needs to be highlighted to make a statement.

Were I were to choose a "white", I'd switch over to B.M. and use Steam AF-15 It won't outline, but, instead, softly blend in with the wall color.

If I may....move the red curtain panels to the ends of the rods, so that they are more on the wall, not on the windows.

I would match shade of the island. It's not contrast, it's grouping, but your looking for opinions and it's a no brainer to me
