I just decided to switch from original idea of laminate over to stained concrete on a little 850 sq ft new construction granny flat rental we are building. I have already picked out the wall and cabinet colors and don't want to switch at this late date. I am using white on trim/doors and 2 shades of light gray on cabinets and walls. What color concrete stain would be best? Grey colored concrete stain in addition to gray walls and cabinets seems like it would be too blah but what do I know? Not a decorator so not much! Thanks...
