Our floors will be polished concrete.

You start here.

Every color of gray belongs to a hue family.

You want your wall color to be from the same hue family as the polished concrete floors.

This is my favorite SW color strip...

If I had to pick one:)

Try analytical grey... my whole house is painted this color.

I just painted our bathrooms and laundry room SW Colonnade Gray. I love it. The rest of the main living areas are SW Outerbanks because I wanted warmer tones for those.

We did SW Morning Fog for the whole downstairs. Has slight blue tint. Wanted a little darker in family room but didn't like tge next color in its "family" so the great people @ SW made me a sample of SW Morning Fog 150%, was the perfect shade!

Grays are very tricky and very dependent on your natural and artificial lighting. If you want a pure gray with no undertones, I would suggest starting with some sample boards in SW Agreeable Gray, one of the best gray or some say greige colors out there. Also, SW Useful Gray. SW Worldly Gray is lighter version Mindfful gray. So depends hugely on your lighting and the depth of color you want.

Lori, I agree we need to decide based on the floors once they are finished. I was just hoping to start compiling some options so I can start seeing them in our lighting to help make a quick decision once floors are done.

I want to keep it really light and airy - am looking at first star, eider white, or egret white. I think the SW standby grays like repose gray or agreeable gray may have more saturation than I want.

Anyone have experience using one the SW white grays??

Yes, depends on which ones you are considering. In the wrong light, they can look dirty. Again, you have to make up sample boards to test in your light especially off whites and grays.

Grays have different undertones and hence you need to make sure it work with your existing stuff. Check out Maria Killam on Houzz or her website to understand better

Since you have time to work on this... and since every color of white and every color of gray belongs to a hue family, you can start by compiling a range of Sherwin-Williams off-white and gray paint chips.

Register here to order large Sherwin-Williams chips online. It's free, they arrive in a few days.

The lists below are full spectrum ranges of off-whites and grays in spectral order (rainbow). Arrange the chips in this order and just like how they're plotted on the color wheels below, you'll see how the colors flow in a spectrum of white and a spectrum of gray.

Using these ranges, you'll be able to test and compare a full spectrum of whites and grays in your lighting to get an idea of what you like. When the floors are done, compare the gray chips to the floor to help you determine what hue family the floors belong to. Once you have the hue family identified, you can then move on to finding the exact paint color you want, lighter/darker, more or less saturated.

Just painted our entire interior Tinsmith by S-W and love it!!!

I have to make a note of that color. It looks spectacular, especially with your trim and wainscoting. Nice job!

We have SW Agreeable Grey as the main color through our house. I'm partial, but I love it!

Thanks, Flo. We had it down to 3 color, but this was my favorite. S-W's design consultant came out for a one-hour appointment, I showed her the 3 strips, told her I liked Tinsmith, she agreed and was gone in 10 minutes!

This is another view of a room in Tinsmith.

A key element that makes that work is the whites. I like it.
