Finally, after a few weeks of going back and forth, I have decided to go navy blue in the dining room and not the grey similar to the primer. I think it will be awesome and if not, I can always re-paint.
I have been going crazy with so many shades and samples of navy blue paint and I finally found my color: BLUE VELVET by ACE Hardware. It is a rich blue-black color. Now for a twist, I have decided to paint my ceiling grey like the primer but a little lighter. Just for visual interest. I am going to add trim and a medallion eventually. SO much to do!
