Bottom left...

The floor is chosen first then at the end of all the other choice you choose wall color. I for sure do not like the red on the left.

I would choose the warmer brown. I would not choose red or gray. Gray is a past trend and red is a trend from longer ago that is such a specific taste that it could drive away buyers when you go to sell. I know it would drive me away. Very light colors are the current trend, but trends in floor colors flip flop back and forth between light and dark. A medium color is the most durable if you are trend averse. You can find a paint color to go with whichever floor you choose. Don't let the wall color drive the floor color. I don't think I would put Simply White with Gray Owl anyway. Look at Chantilly Lace.

far right

Top right also is ok. I think some who are saying just "left" or "right" don't see there are two rows so they have to say top right or bottom left.

There is virtually no paint that doesn't work with a medium deep brown floor, And I mean forever, not only in the gray owl paint decade.

No I didn't click on yours

Other than the grey and reddish, the others will work with really any paint color. Base your decision on more than wall color, as paint gets updated and flooring is a long term commitment.

Think about your home’s feel, your style, furniture and decor and if you lean towards a darker or lighter stain. Narrow down to your favourite two and look at inspiration rooms that reflect your style.

Another idea is to purchase a box of each (that can be returned) and lay them down to see their visual impact.

I like a medium brown wood. Jan's pic of the wood floors looks great! They would go with anything.

Grays and browns seldom work well together. So, I would tend toward lighter colored floors.

Have to strongly disagree on that. The lighter floors are much harder for paint color. Meaning grays with them, can cause them to lean yellow. Medium brown hasn't shown me a color that didn't work. Not one.

Grey's and browns don't work together? Well....that explains my hair...

The first is my choice for the long haul. It is lovely and warm.

Guessing you haven't painted yet? Suggest B.M. White Dove (instead of Simply White, which does have a creamy yellow undertone) with the Gray Owl, if you go with my choice of floor.

Here is a kitchen with white dove painted cabs and Gray owl walls. Also wood floors. In some photos they look dark and others reddish. I love the combo!

Honestly I think almost all of the wood floor colors can work with Gray Owl. More information would be needed to choose one. What is the style of the space? Is there other wood or painted cabinets involved? What furniture? As JAN said, a medium brown is probably the most versatile and classic and the gray tone is probably the most trendy and likely to go out of style soon. I also think the gray wood is the worst selection with gray paint since it's a blah sea of gray.

Found a flooring for my gray owl

It's a beautiful wood. It will look nice with many paint colors!
