?"...list popular"? Do you mean for a flip?

Everything regarding "popular" - like real estate - depends on location, location, location.

In conservative areas, dark flooring is still very popular. In other areas (like LA and NYC) super high-gloss white has already come and gone. Other areas are right in the middle of the "gray trend" whereas others have already moved away from cool tones and into light warm tones.

And that can be found inside a 500km radius. Imagine the variation if you are in Georgia and someone from California answers this thread.

A little bit more information is needed.
