Laurel Bern just did a ceiling post on her blog.

If you had not just painted, my first suggestion would have been to close up the smaller opening. As that probably isn't something you want to get into, I'd paint it to match your trim, or a very pale blue (my choice).

I re-paint rooms fairly regularly, and change colors, and I do it myself. I don't love painting. Painting ceilings is hard! So... I'm a big fan of all-white ceilings.

Do check out Laurel Bern's blog post on ceilings as mentioned above. Here is the link My ceilings are giving me nightmares during the day

Reading that blog post makes me want to rip out my tray ceiling. I have the same double tray issue you do plus a lower ceiling portion in front of my windows and French doors out to the patio. My center portion is not as wide, but the number of stripes is the same. What you did for the short term may be as good as it gets.

My room was wallpapered with a floral stripe and two rows of border around the trays. We painted it ll the same in a pastel/off-white but I got bored quickly and wanted more color and a blue ceiling. We did that and started the blue at the 10 ft level to avoid some of the striping (and no wallpaper borders!) so it's kind of like yours is now but with a pastel blue on those to layers and the very top. It's so much better than it was, but from time to time I think about changing it again. The blue is pastel and the contrast with the layers of crown trim is less than with the wall paint, so it may be better than the wall color -- but I don't love it. I'm still not sure how to deal with that ceiling. If you figure it out, let me know.

I like it best with the entire ceiling, including trim stripes, painted one color, or with only the topmost part painted a different color, especially the pale blue posted above. One of the ceilings in Laurels post is also light blue, though not a tray, and I think it looks really nice.

Sea Salt is a lovely color. I would consider using that on the ceiling.

painting that all white would be a waste of a good feature. I'd prob go dark if it was in my room. but here are some others

Love a pale blue ceiling...then the skies are always clear...looks like it would work with your bedding too.

Here's how we handled the tray in the exercise room.

And here's the soft blue in the guest room....

I like the colors you have.

Maybe consider closing the middle.

I played with colors on the ceiling...though with crude tools. But just to give you an idea of how the various options might work...there is not right or wrong...only what you like.

I went with minimize and installed this fan in both my bedrooms. Happy with it so far!

I'd also consider a simple, light wood fan in your room.

We did a chandelier and I love it, though I do miss the fan. We got a narrow tower fan -- does the trick but prefer a ceiling fa over the horizontal breeze.

You could do something like this fan/chandelier combo-- if the size works.

I see this post was from 2 years ago, but curious to see what you landed on as the solution!
