Really there is no way of knowing they look like natural walnut to me but the picture is hazy and colors on moniyors are not reliable.

Your flooring professional will make up colour patches on your site-finished floors. You will pick the colour you like the most. Then your installer (not some guy who swings a hammer for the general contractor) will refinish the floors as per your request.

And always have a single coat of the finish added to the colour patch. Many finishes alter the colour which means you won't know the REAL colour without having a coat of finish.
