You test on site. Your light, your exposure, the trim..., the carpeting....all will affect how you see whites in the space, and they ALL will be different at different times of the day. "They" can use any paint you specify, just expect to pay more, or get a different "they".

I like Chantilly Lace /Ben Moore.........but that's a guess. I'm not in your space. I prefer Ben Moore......always.

Any white will be better than the color zoo. What will be your BEDDING? Best start to a bed/bath scheme , usually : )

We’re in a bit of a pickle regarding on-site testing (what we’d normally do). We get keys on Saturday, but not sure what time. We also need to tell the painters our paint choice on Saturday so they can get started/finished before we move in.

We have to take a little leap of faith here.

Bedding pictured.

Painter uses S.W. Paints have formulas and S. W. can match. I use B.M. and if I were doing your room, with natural wood work, and a south/east exposure, my white would have a very slight gray undertone:

I did find this example:

Honestly, I would pick a few white samples (probably too late to order on Samplize) and paint some large poster-boards. As soon as you get keys on Sat, take the boards and position them in different areas of bath/bed. Are the painters going to start Sun? No, more likely Monday, right? I'd observe the whites in morning/afternoon/evening/night lighting and then decide. I imagine you can tell them the color on Sunday.

Love your bedding! And I envy your spacious bedroom and ensuite. Here's another idea which might be a good starting point: use SW's ColorSnap app to find your bedding's paint colour matches. There is a white in that print, right? The app will pick it up. Benjamin Moore has a similar app as well. Take more than one picture in both natural and good quality artificial lighting to get some options.

With the warm wood vanity and tiles, I'd go with a warm white rather than a stark cool one so that would mean BM's White Dove or Simply White over Decorator's White, for example. From my testing of a few BM whites on canvas boards, BM Cloud White is a nice soft white that doesn't look stark or yellow in my light. As others have said though: lighting is everything when it comes to paint colour and whites can be notoriously "fickle" in that sense.

Best of luck with your decision and congrats on the new house! Hope you'll report back. :)

IMo why white at all and honestly natural light in a space you only use at night is really a none issue IMO. I would choose a pale blue from the bedding and the ceiling and walls all the same Or go Chantilly Lace IMO the artifial lighting usually is the culprit when whites look off , Make sure all the lighting is 4000K Led then at least the colors stay true.Gcubed has the right advice

I would not attempt ceiling and wall the same. The trim is oak.... The PALEST turqouise on walls. or the palest gray _ a whisper of color at best. Stay AWAY from "warm" whites.

Nice with all the wood........ Add a lot of fresh white to the linens

“4000K Led then at least the colors stay true.”

What about when you turn the lights off?

"Stay AWAY from "warm" whites." Why, @JAN MOYER? It will bring out the yellow in the wood?

"...honestly natural light in a space you only use at night is really a none issue IMO."

Don't know about you, @Patricia Colwell Consulting, but I'm not a vampire and happen to use my bedroom during the daytime. Even if it's just bringing up clean clothes to put away or getting dressed in the morning, I like the idea of appreciating my bedroom with my eyes open. If time spent sleeping trumps everything in bedroom decor, might as well paint the bedroom black. :)

I think white is a great choice until you live there a while. Then decide if you want a change. I most definitely wouldn’t base it on matching a color in your bedding at this time.

These are all SW Greek Villa. I can’t say for sure, yes, use this, not having seen the room ... but am thinking it might tick all the boxes.

The colors in the bedding are cool. . The wood, is warm , hints at orange.......it ( trim )will look more so with a warm white, and will fight the cool of the bedding. Erring on the "green" side of blue will enhance both the bedding, and the wood.

You don't need 4000k lighting in a bedroom. Please no, unless the surgeon is coming : )

Add a DROP of wall tone to a clean white ceiling. ...........

Want truth? I'd paint out the wood trim in a single heatrbeat. PS......WAY less color than the photo, on the ceiling.

About a quarter !!!! of where that guy is brushing on........a "kiss"

Here is our SW facing room with the same bedding as yours. We have golden oak pine trim with golden oak furniture (wanted to use the existing furniture). The walls are SW Wool Skein.

With all those ceiling angles and wall changes , which ever paint you chose will look a bit different over the course of the day.

Since things are so up in the air and time is ticking away, I think I'd have those painters simply prime both rooms very well. Live with that for a while and you'll make a better overall decision with less pressure and the opportunity to order some large peel and stick samples from samplize.com to try in your spaces and on all your different walls. .

Was coming back here to suggest exactly what @decoenthusiaste is suggesting! Especially, if hiring out the painting. You don't want to end up with an expensive regret.

@JAN MOYER, interesting comment about the green not bringing forth the warm tones in wood. I know that blue is complementary to orange so often that pairing highlights both colours. Also, I notice the white walls in the first inspo pic you shared are on the warm not cool side.

Yes.. The white is warm in the picture. ......There is no oak/wood trim. It's a soft cream and green palette. The "blue" is limited to the settee Green and "red" are directly opposite one another on the color wheel Extremely complementary. : )

You notice I said I'd paint the trim "In a heartbeat..............to a white. As you know those can be warm or cool..

In the end , it's paint. Not a hole in the wall. I pulled the least dominant shade in your bedding - that pairs nicely with existing trim.

We’ll eventually paint the trim, I’m sure. The initial goal is really to have the walls not be green and yellow. Our style is more on the Scandinavian / Japandi than anything else which is why we’re thinking some sort of white.

I'd not have guessed your style preference from the bedding selection, that I will admit. I never use SW, so I can't advise a white. Really a thing that is best tested in the space. But any white will nuke the zoo, for better.

Fro me, that would be Ben Moore and Chantilly Lace. I also believe a painter "uses" the brand and color you want...... charges accordingly. Or you go HIS way. This is nothing to do with quality, it is contractor discount. Period. Ben Moore is better paint : )

Think long term about your style. Rooms are more than paint. Quite different, below no right and no wrong

Totally fair, @JAN MOYER. We’ve had the bedding for years and our style has evolved. Found out last night that we can get into the house earlier than expected, so we may have time to test some paints.

@robbiewellman, great news about having time to test some paints! If there's no time to order Samplize, paint canvas boards you can prop up on every wall rather than test the paint colours directly on the wall. (In my experience, bedding is easier to change than paint so my vote is a versatile white.) Good luck again and hope you'll keep us posted.
