Buy a large piece of foamcore. Paint it yellow. Move it around the rooms you are considering for accent walls.

Or just have it all painted white because then you can easily add an accent wall later, once lighting, flooring and furniture have been installed.

I personally would stay away from yellow undertones. https://www.behr.com/colorfullybehr/picking-the-perfect-white-paint/

Paint the condo one color in eggshell finish with a different color for trim and doors in semi gloss. Geez NO YELLOW

What's going on in the bathrooms and kitchen?

Your selections lean WARM.

I would consider a more neutral color like Silky White with Polar Bear Trim & Doors

Are you keeping the tile? Will you be adding flooring?

You can't select accent colors without knowing what the colors of the furnishings are. Do you have them?

You can stilll have a great looking home with all the walls the same color by just confining the accent colors to art and accessories.

I would not paint accent walls, they are no longer trending. Plus it sounds like the home would be too choppy. Whole room paint colors are more contemporary and fresh.

For walls and ceilings, I prefer a Flat or Matte finish over a sheen such as eggshell. Flat has more depth because there is no shiny surface. Semi-gloss or satin for trim, yes.

For the guest room I would consider a soft grayed blue because of the blue light coming off the water.

For the rest of the home, an off-white sounds nice. I agree no yellow.

We chose Kelly Moore Swiss Coffee (off-white) and love it but they are out of busiiness....other paint companies can mix the formula for you if you want a sample.

Thank you, Tracefloyd! Very helpful!

Beverly- Thank you so much for your detailed and very helpful answer. I can make a million decisions each day but paint color on walls is sadly not one of them. :-)

We've removed the entire flooring, incl. the tile. Our new flooring is https://www.staymorfloors.com/floors/p/sandstone 

In the rooms it's tending towards warm, not grey.

No, we do not have any furnishings at all yet.

The floors look good with Behr Swiss Coffee.

A bright white ceiling will make the color pop. A ceiling and trim painted the same color as the walls is very serene.

@tracefloyd I found this on Kelly Moore Swiss Coffee versus Behr equivalent: https://coloretica.com/color-match-tool/kelly-moore/kelly-moore-match-to-behr/swiss-coffee-23-equivalent-winters-end-2077

Here is something called Behr Absolute Zero...very nice for the guest room

Hi D M!

A few possibilities photos?

Yellow walls are a favorite of mine, used by the great decorators, think, David Hicks! who used buttery and muddy yellows as a neutral. I second apple_pie_order! if unsure, test the color with a sheet or rolling sample!

A little inspiration follows …

And just quickly! This is from a textile site but i use the charts in decor! Should you dive into the virtual rabbit hole of online color try out, always go with color codes in hand!

D M i so love yellow, hoping you keep it in decor if the walls do not work, but it has such great flexibility and warmth, hoping you let loose your creative muse and play!

@Abby HeartsBeauxArts I agree with you. Yellow is one of my favorite colors, it pairs with just about anything. I'm an artist at heart (photographer, water color etc.) and selecting the perfect color is very important for me but I'm so picky that it's hard to make a decision. I LOVE the website you sent! Thanks so much!

D S You are most welcome! My background is historical textile restoration, and this morphed into decorating! Practical applications seem the most helpful when determining color palettes — art, photography indeed!, textiles etc. help you “see” further!

The Behr Swiss Coffee is very nice. As mentioned by @apple_pie_order, you could do a color such as that everywhere, and then later decide on other room colors and/or accent walls, etc.

I am a yellow/gold lover, myself... very much so. Maybe that is why I rendezvoused with a place that is full of it! LR, DR, kitchen and hallways in my current apt are done in the yellow gold. I love it.

So when I see that someone is interested in a yellow/gold wall color - I am all over it!! :)

AI and I are up at the wee hours here in NYC - and going for the gold! :) I tried to capture some of the views you describe.

I asked for tiger art - and I definitely got it!!

Reminds me a bit of Farrow & Ball’s Cat’s Paw.

So much fun.:)

Those British drawing rooms in yellow and filled with antiques are nothing like your space so yellow walls will have a different effect for you. Probably a more modern feel with your architecture, maybe MCM furnishings to go with your yellow.

I'm a big fan of neutral paint for walls. If you paint, often, in 10 years, your paint will be out of fashion and finding furniture or decor that goes with it is hard. Even if the same color is in, it will often be a different tone. Lighter, darker, bluer, greener, grayer turquoise might make it hard to match, even if turquoise and beachy is still around.

It's a lot easier to sell a house with neutral paint.

I don't see any point in "consistency" between rooms, unless you have substantial views from one into the other. And then, I'd just make sure the colors are not clashing.

Some paints really light up a room. Paint a warm color in a room with little light. I have a room with north-facing windows, shaded by trees. We painted it BM Marry Me and for the first month, my husband and I kept thinking I'd left the light on in the room, because even the weak winter sun on a cloudy day made the room look warm and sunny.

I don't know how all the rooms will be furnished but I definately wouldn't do any accent walls. Behr's Swiss Coffee warm white can certainly work throughout or one of the more neutral whites:

Matte for the walls and satin or semi-gloss for the trim.
