Considering we did a pretty darn similar set of colors, I'll give you some recommendations and photos. Actually, our floors are provincial from Minwax and our all around wall color is Crisp Linen White from Glidden (color matched in Olympic). Here's probably the best photo of just the wall and floor Better shot of the kitchen (except the blurry light gunk on the lens) I would suggest you look at Sea Salt from SW for a muted green/blue, maybe Palladian Blue from BM, we used both of these colors (again matched in Olympic zero VOC) in our upstairs bath. Terrible construction photo, in terrible light, but Palladian blue on outer wall, Sea Salt in the tub area. SS is just a bit lighter and less blue. Palladian Blue main area: Sea Salt around tub (poor lighting, I know):

SJ McCarthythank you for your very long process description and NWFA suggestion. With all the risks that proper preparation requires I think I just have to dodge the bullet and pay someone to do it. It really isn't just applying the stain with a brush kinda thing. I emailed seven companies. Four from NWFA and three from neighbors' recommendations. Just few moments ago I had one of them here to look at the stairs. He is certified has all the proper training and certifications. He seemed knowledgeable and explained all the steps. He will have to re-sand. It will be a 3-4 day job depending on how many stain coats are needed. He uses DuraSeal stains and Bona Traffic HD water based seal and has training to work with those. Each coat needs 24-48h to dry. Then he will have to do another 2-3 coats of the seal. His professional opinion was also that the stairs did not turn yellow because of the covering, but they turned yellow because the previous company used an oil based poly. They might have also applied the seal when stain wasn't dry enough. He is almost certain that the amber coloring from the photos is oil based. He never heard of floors turning yellow because they were covered. That being said, he told me I have a good chance winning a small claims court. That the photos should be sufficient. The stairs were first finished in March, we covered the newly stained steps with protective brown contractor's paper, since there was still construction and painting happening. In July we discovered that there is yellowing present. Since July I've been contacting the company to fix it. They refused because they claim that it is not a warranty issue since it is our fault that we covered them, and that is what caused the yellowing. However, the best changes in court would be with two expert opinions. What I should have done was getting an inspector's report and document the yellowing properly. My mistake was sanding the stairs down before finding a new company. Now I cannot get an inspector to examine it. The reason I had my trusted carpenters to sand down the entire yellowed staircase was because our remodel has finished, and I didn’t want a yellow staircase in the house. I was also worried someone else wouldn't be as careful, and do more damage on brand new painted baseboards and stair skirts. Most importantly I knew sanding it down completely will be a huge mess and didn’t want all the dust on our stuff. I wanted to move into a clean house. Now, there will still be sanding just not as much as the heavy sanding. Even the walls were covered in sand. It was awful...

Bless your heart @M Miller. I did actually add to the discussion. I read what the OP wrote about not wanting to change the wall color, I liked the options Celerie provided and I rolled my eyes at the comment from some one that said unless they changed the color of the walls that room would forever be miserable, like some Grimm Brothers old crow casting a curse on the homeowner. But I’m one of the lucky ones that believes the age of a house has nothing to do with what colors you can or can’t use (unless the OP mentioned this was a period appropriate B&B? An historic house museum?), everyone sees color differently meaning not everyone thinks dark gray is cold or that a cold gray room isn’t desirable, or that a color found in nature like a storm cloud or angry sea is somehow dated or overused or that it limits how you should use it or where or if you’re even allowed to like it.

You don't want to pick the floor color in isolation. It has to work with the elements you are not going to change. Are you keeping the wood beams? Are you keeping the exposed brick? Are you planning on painting? Do you already own furniture that you will be using long term or will you be buying new in the next few years? I suggest using some online or phone apps where you can upload the picture of the room and change flooring materials - test different looks in your room and decide what color you are aiming for. I think that the wood beams and red brick make your space unique and wonderful, so I would use that to plan the rest of the space (flooring stain, paint colors, furnishings), but you need to decide what you love and how to make it work in your home.
