Color makes one space into two rooms

I am seriously considering painting my dining and living room a color. In the rest of my house (besides bedrooms) I am using BM Navajo White on my trim and ceilings, which is a match to my kitchen island cabinetry. Any thoughts??

If see two rooms in the picture. If you paint the two in different colors, you will see two seperate rooms instead of one space.
