Apparently, nobody else wants to venture a guess...
But mine would (wood) be that it's good old fashioned red oak.
For a while there, we couldn't GIVE an oak floor away, but now we're producing more all of the time. Although the demand favors white oak, currently.
The color... could be any of several depending on what brand was used.

This floor was likely "sanded in place" and our forte is producing custom prefinished flooring... so the products we use most frequently wouldn't apply.
We COULD, for example, manufacture the same specie & color in a prefinished format.
