I believe it would be nice to paint it white.

The way the trim is painted draws attention to it, and that is something that should just blend in. I would definitely paint out the trim and since you have painters in there, make whatever other changes you have in mind.

my thougts too. It draws to much attention to the top and bottom and cuts the space. I will have to hire painters to go in after we close. Changing lights ad hardware too. Good thing we love the location!

It's striking, but that means you have to love it. I'd paint it to match the walls, in fact, to help the room(s) feel higher.

I like it. Very unique.

If you don't like it now, you won't like it ever. Change it to what you want before you move in, otherwise it will be a pain to do later on!

i think its chic.

once you put up artwork and get your furniture in there, it will minimize the extremeness of it.

if you look in architectural digest and other high-end interior design magazines, black or charcoal trim is often shown.

literally an article from May 1 2017 that looks just like your trim: http://www.architecturaldigest.com/story/contrast-molding-paint-trend 

HI -- I have never seen the need to have rooms all out lined with a different color unless the house is an historic colonial . Your new house has modern features in light fixtures and hardware and glass so I don't like the trims in a modern house . See if the builder can re-paint all the trim to a white or the same color as the walls --- which ever you like . A lot of new houses also have too much trim everywhere too.

I'm sick of seeing gray everywhere BUT I like this, this is a unique addition of gray in a home, I think it's really chic.

if the trim was white and the walls gray, with that dark floor it would be so much darker in there.

Totally a matter of taste. If you don't like it, paint it. So much easier to do before furniture is in place.
