What a sweet project, congratulations. :)

The F&B site has Vert Du Terre with Lime White and Slipper Satin, among others. Maybe a couple to consider (if they work with your trim … or repaint the trim with whatever wall color you choose) —

Monitors aren’t exact, of course, but this shows them compared to the greige:

What are the whites you have now (trim and tested on wall)?

Cool wallpaper. Is it up yet? Might be easier to pick your light color if the wallpaper was already installed because it will reflect its own color into the room.

I have one coat of Benjamin Moore Gardenia on the walls now, looks a little sloppy because I haven’t done the second coat

And thank you all for the suggestions! I’m really curious if the accent wall and wallpaper will shift how the Gardenia looks so maybe I’ll finish the second coat, do the accent wall and re-evaluate

Please show us afters! :)

IMO the same green on all the walls and please change that light fxture it in no way works with beautiful F&B paint .I woud just do the trim and those doors in a light color and hoestly stay away from the yellow based white maybe strong white for nice crisp look for the trim. I like the wallpaper but it does not say child to me but it will be fine until the child tells you waht color they like this year so be prepared for many changes . I use very neutral wall color in kids rooms when they start wanting colors and then use decals and those color of the choices for stuff eas to change like bedding

I would use Vert Du Terre on all the walls.

Stunning wallpaper. In the second pic down, there is a nice blueish green sample to the right of the wallpaper swatch. I think the rest of the room would look fantastic in that color. I think white is too much of a departure from the accent wall and is not going to make the room look as seamless as a color will.

All of this wil change depending on the kind of bulbs you have in your light fixtures. And, at different times of day. I'd be sure to account for all of those variables.

Gardenia has a pink undertone, so that's why it's not working with the wallpaper. Sometimes the undertones aren't obvious until you put them next to something else. F & B makes beautiful paint, but if it's too expensive for this project you can probably find a BM color that would work. Maybe Feather Down? It's hard to say since colors aren't 100% true on monitors.

Update! Almost done installing beadboard vert du terre! Still tbd on paint

I love BM Bleeker Beige!

Lovely colors and wallpaper! I’d use the wall paper on all walls (unless cost prohibitive, on which case I’d paint the same green as headboard or just a nuance lighter)

Put the paper on four walls above WHITE wainscoting, all four walls.

Try Ben Moore Simply White for all the trim.

It's a nursery, right? Not your library. Children respond to colors you wouldn't consider in the rest of your home: )

Wallpaper is exorbitant so one wall partway is all I can do!

Well. I'd go for a less expensive paper....or stencil, or great decals. A child outgrows a room in a mere few years.

Not to be the bubble burst? I'd set that paper aside for something else: ) But that's me.

Elizabeth, it looks so wonderful and charming! Great job! I was hoping you wouldn’t get talked out of it.

I’ll bet it makes you smile. :)

what a cozy beautiful room!

Looks great!!
