Accessible Beige by Benjamin Moore would be a good beige as it has a slightly pink undertone that would pick up the color in your pillows. I wouldn't go a light blue, as that seems more in keeping with bedrooms, IMO.

Everyone has their own individual tastes e.g. the three examples you have provided are not my cup of tea. I prefer to keep the walls neutral and add treasures I love to express my personality. My personality is displayed in my entire room not just the walls.

I was about to say grey until I read the last line. What about a light brown carpet?

The island benchtop and countertop used is White Snow from Uniquartz
