In the above photo, the three ceiling beams on the bottom and the space between is painted. It doesn't look all that different than the primer; it is semi-gloss over the primer. It does not seem to have a sheen. I have experience with this white, I used this very same shade in the rest of the house on the interior doors and ceilings, but it doesn't look the same in northern light. It looks much whiter and less warm.
It's on the left ceiling in this photo. hmmm... I do like it on the brick and the planked walls.
What a dilemma! I have some furniture for this room that I kept somewhat in mind during planning, but it is still hard for me to imagine a finished product because it is big, blank space of 295 square feet, except for the laundry area.
