If those are the only 3 choices. The top one. But I would look for something slightly lighter than that one.

What's wrong with the wall color you now have? It is a warm gray from the looks of it on the monitor. And flooring should NOT be a change from the kitchen flooring. Continue it. Even via refinish to all other areas........perhaps a bit deeper, but you never be completely rid of the red undertone if that is what is bothering you. The red casts a tone on the mindful gray cabintery, making it read a bit cooler. Teh counter tops are very warm in tone. Maybe you can elaborate as to where you are trying to "go" beyond ridding yourself of carpet?

Unfortunately, a gray-toned floor will hold you hostage for picking wall colors, backsplash and counter. It pretends to be a neutral, but then the reality hits after it‘s installed, that it’s not a neutral. If you still can, I’d pick a floor that is a more natural wood color. In any case, pick the wall color LAST, after you’ve chosen counters, then backsplash.

Almost any color will work, as long as there are no yellow tones to it. Personally, I would pick a white color with a hint of green or blue in it.
