Maybe some options…

I know you said Benjamin Moore, but you can always paint match. I am currently mad-loving SW Dutch Tile Blue! It does look quite different based on natural lighting, but I love it either way. Their website shows it fairly accurately in sunny vs night - you might want to look at it.

Ummm…maybe she likes blue? 😂

So many beautiful blues! You could try Jamestown Blue, Buxton Blue, Yarmouth Blue, Cape Blue, Franklin Lakes, Saratoga Springs, Blue Stream, Colonial Blue, Northern Air. All are blue/gray-blue. But you need to view them with everything that's going with them--flooring, counter tops, etc. In your room with your light.

Slab cabinets are best done in laminates, foils, solid acrylics, etc. Not paint. While paint offers more options, its the easiest to mess up, and the easiest to show wear and tear. Any cabinet maker who paints slab MDF had better be very very experienced in finishing. Not a lot are experienced in slab MDF.

At best, a slab door in blue, would need to be a VERY deep blue......or look quite misplaced.

It should also be a factory finish.

The paint in a very deep blue with soapstone? Nope, not the best idea.

Perhaps show an inspo of exactly what you are going for, as it seems a style/color mash up. Lighter tone would suggest a more detailed door

Deep? A lighter counter top, less traditional

Thank you for your suggestions. Here is a photo of the layout plus the sample blues we have painted. Starting from the left, Yarmouth blue, Blue nose, old blue jean, denim wash, northern air and mt Rainer gray. The floors will remain. The window wall will have no uppers and the walls will be painted white (TBD). The windows face NW so there is good evening light but mid day less light. The cabinets are being made and lacquered by the cabinet company. They colour match to BM. Was curious if people have used a blue with a soapstone counter.

Where is your inspo for the space?? What IS your flooring?You are shooting fish in a barrel.

Your blues? Light blue makes no connection with a slab door. It DOES with a more traditional door.

navy or the darker blue w sopastone is a nice classic look..but it depends on details. its very much "little black dress "

heres hardware/some other white surfaces/ pendants etc to make the darker island top/ darker perimeter cabinets all work so well. ...even in small space.... can you show what is going on?

Dark on dark is going to need 10K of electrical work for a much better lighting plan, so you can see that the black and navy are actually different colors. Without enough light, you can't tell the difference.

For your kitchen cabinets, Benjamin Moore offers a variety of blue shades that can create a beautiful and stylish look. Here are some recommendations:

• Beach Glass: A soothing blue with hints of gray and seafoam, perfect for a calming kitchen atmosphere1.
• Blue Hydrangea 2062-60: A cheery blue that highlights lower kitchen cabinets, pairing well with greenery2.
• Smoke 2122-40: A versatile blue that can fit into many kitchen styles2.
• Caribbean Mist 2061-70: A light and airy blue, great for a fresh and vibrant feel2.
• Woodlawn Blue HC-147: From the Historical Collection, this airy blue brings a sense of history and elegance

I hope this is useful!

Blue slab doors plus soapstone plus waterfalls is a mixed up mishmash of styles. Sort out the style indpiration girst. Then sort out the materials. Your higher end slab door companies will mostly use thermofoil, or HPL, not paint.

This is a Sherwin Williams color, but we used it in our laundry room slab cabinets.. Delft.

A mashup of styles is also know as eclectic or thinking outside the box. It does take more skill to pull off, and isn't frequent on Houzz. But, don't let that stop you from trying. There is no reason .you can't have light color flat front cabinets. And no reason you can't try to have soapstone with light blue.

I'd select your stone first because you'll have so many paint colors to choose from in trying to find a good match. If you go with paint color first, you'll likely back yourself into a corner with fewer stone options. Soapstones come in a lot of colors - are you thinking more black or lighter?

Here are some images of blue kitchen cabinets and soapstone counter tops.

Notice that yes, most of them are dark blue and with doors in a very simple shaker style but slab drawers. They are also mostly traditional/farmhouse/transitional, no modern kitchens showed up on the Houzz search. Only you can decide if this is the look you want.

From the photos posted by Diana and Kendrah, I think your blue + soapstone idea can be stunning. Just don’t call it any particular style (“We’re doing a modern kitchen in blue with soapstone.” Or “We’re doing a farmhouse kitchen….). Just do what makes you happy.

I agree the choice of stones is more limited, so get that picked out first. Then find the right blue. Endless options there…

Thank you Kendrah and Diana for finding pics of what OP is proposing. Love them!

“A mashup of styles is also know as eclectic or thinking outside the box. It does take more skill to pull off, and isn't frequent on Houzz. But, don't let that stop you from trying.”🎯💯

Thank you everyone for your comments and posting the images! The images are similar to the look we are drawn to, it's just hard to pick the right blue. So was curious if anyone has done a similar design and had a blue that they recommended, knowing it might not be the exact one we choose, but may be inspiration.

For inspiration that is more eclectic, less mass produced, less American, or deviates from a cookie cutter aesthetic, I tend to look outside of Houzz and do google searches, pintrest, architectural digest, and clever (which is part of AD). Here are some pics I found in those places. Unfortunately, I don't have paint names but perhaps the pics will help get you closer to an idea of intensity of shade and undertones.

When picking colors, I often go to Farrow and Ball because they don't have 500 kinds of blue. I will find something I like there and then google a farrow and ball benjamin moore match. Sometimes the match is off, but if I scroll down to the bottom of the Benjamin Moore color match page, it will make suggestions for others like it. It is sometimes a fruitful rabbit hole to go down.

Once you select a color, will your cabinet person make a sample door for you? I have always found that the paint color looks different in the cabinet maker's finish than on a chip. It is important to play with the door sample in the light of your home to see how you like it in there.

What are the floors?

Also google image search "best benjamin moore grey blues" and you'll find a lot of collections that people have put together, like this.

Thanks for those images and suggestions. Great inspiration. We've purchased some MDF slabs and done some colour samples ourselves and next our cabinet company will do a sample cabinet. I'm just struggling to pick, but ultimately will just have to make a decision.

Pick your soapstone and THEN pick your blue.

There are thousands of beautiful blues but your stone will be more “one-of-a-kind”. At a minimum, get a piece of it so you can look at blue paints with the soapstone IN HAND. Not every blue will be perfect with your soapstone.

Don’t guess.

Also, why just Benjamin Moore? A good professional quality industrial cabinet coating will be able to match SW or FB, etc. You are not planning on using actual BM wall paint on your cabinets, right? Because no pro should do that.
