I worked in paint at Home Depot for years and one of the nicest neutrals is informal ivory in their Behr paint. In sun it has a very light yellow cast and at night it has a lite warm beige cast.
My old house was that color in all the connecting rooms and when I moved I liked it so much the new house got it too. It is a great backdrop to hang colorful quilts and pics on the walls without taking away from the colors.
