White.

Here is how the ceiling will appear if you paint it.

My first thought was to stick with the trim color. @BeverlyFLADeziner mock up she so nicely did confirms that for me. I do like the Sea Salt on the back porch ceiling & have a similar look on my home. But, with the brackets & then the shutters too, there would be too many things going on with the added color on front porch ceiling.

Is that a porch or a large overhang?

I usually advise a sky blue color for a porch ceiling but here in Michigan that would be grey.

Seeing more context I would say stick with the trim color. Interesting design in a positive way.

I agree with same as trim--really nice house!!!

In the South, we paint all our porch ceilings Haint Blue. Haint as in ghosts -- it's an old superstition.

I like the blue with the white brackets and trim... and it makes the interior space interesting.

This style of architecture -- at least the porch and brackets, is common in places like New Orleans.

Yes, Mrs Pete, haint blue! We’re pretty far south, all the old houses have it.

And PPF, that def was the inspiration. We’re not too far from New Orleans.
