@Lisa Saunders...
Someone DOES make a grey rustic floor... engineered or solid.
And in any "shade", specie, or style the Client wants...
And although Cancork has done a great job "breaking it all down" on the subject of engineered floors, I'll just add another point... many of the imported products use a "substrate" in their engineered lines, which is of questionable quality in relation to health, stability, moisture resistance and other factors... so keep in mind that the foundation BELOW the actual hardwood top layer is a very important consideration
