One suggestion is to paint the wall that connects the 3 rooms with one color and then paint the rest of the rooms with complimentary colors. You might also consider doing this in just the living room and kitchen and paint the flowing wall and all of the hall the same color.
Another way is to add an artificial break in the walls with molding or moldings. Some vertical molding pieces could be used to separate the 3 rooms.
Finally, if you are bold enough, you can use contrasting colors and just paint an edge break. This does not have to be a straight vertical line. You can make the color change at a diagonaled straight line or with a line painted in a long arc. Or you can just paint everything off white and live with it.
