It depends on the actual space and your taste/preference. You know your wall color will look darker and/or different on the ceiling, right? A third option is to do a 50% version of the wall color to use as the ceiling color. Worst case, if you don' like the paint choice you made now, it can be changed down the road.

Have you looked at the photos on Houzz to see versions of each option?

Thanks. I have looked at pictures and do like the idea of it being continued onto the ceiling but am afraid it will feel too closed in and dark in real life. Perhaps the 50% option is a better way to go.

We did 50% lighter of the sage green wall color in our dining room and I really like the effect. We do have white crown molding though.

My house is more transitional but it has open space for kitchen, LR, DR and hallways, sharing a common ceiling which vaults to about 13 ft. in the LR. I have traditional white ceilings in my bedrooms, but I opted for the same color on the ceilings in the open spaces. I was apprehensive about doing it, but I love it. I have SW Antique White in full strength on walls and ceilings. Its LRV is 74, compared to 61.63 for the color you're considering. Yes, it does appear darker in some places, but not all. I don't have crown molding either. It creates an enveloping rich feeling. Sometimes, in certain light, you don't even see the demarcation between the planes of wall and ceiling. If you really like your color it can be the best thing.

If you want to lower the ceilings, paint them a color. If you want to raise them visually, stick with white.

I still prefer a semi gloss white on a modern style home, they reflect so nicely.

Our first home had ceilings painted the same as the walls..maybe a tish lighter. First thing we did was paint them white. The lowering affect gave us neck aches from the ducking!! Painted ceilings is a trend that comes and goes..white is standard and will never date a home. We haven't found painting ceilings to be an easy, fun event...

We have agreeable gray on our walls and a white on the beams and ceiling. Depending on the light, the ceilings look light/white or about the same as the walls. We prefer the lighter ceilings and think the gray would have been quite dark. Yes, the beams and ceiling are the same color...amazing how the light plays with the angles...

Thanks everyone. It sounds like I should just stick to white if I'm going to be using a pale gray anyway. Also, thanks for the picture Jubilante. It's nice to see that the white doesn't look at all jarring against the agreeable gray. In fact it's almost impossible to tell they are a different color.

Our new build is open concept with a vaulted greT room and we went with a SW pale gray and SW snowbound for the trim and ceiling. It looks great.
