I see your dilemma was lost in the maze of houzz. West facing white? You need a blue or green undertone to balance the late afternoon yellow impact. B.M Patriotic White should do it…yes, it is not really white, but I am afraid that any white/white will go yellow on you. Hey, try painting an area…two coats.

What did you end up going with. Would like to see a room in rhinestone.

I think you just need a navy patterned area rug for your seating area. The colors look okay and have a coastal feel. Question: Is the stairwell a darker color then the living room wall? Maybe if you changed the lightbulbs to a white light,(non yellow) it would make a difference in how the paint color looks to you. Cheap fix This PB rug is on sale. It has all of your colors. https://www.potterybarn.com/products/adeline-rug-blue/?pkey=call-rugs&isx=0.0.5765The border is gray. same rug, but in a runner shape (model home) https://tours.stevenjamescollins.com/public/vtour/display/209715

What ??? IMO wall color is decided with all items in the spaces factored in not a counter in a kitchen .
