Impossible for anyone to say without seeing your space, furniture, decor, etc. I put all my sample boards under the furniture and rugs I was keeping, which made it easy to see which samples did not complement my furnishings.

You might want to place them over a white sheet, so your rug isn't influencing the color. Try and find photos of the floor in a room to see how uniform or stripey the stain is across the whole floor.

Once you narrow it down to 2 samples, you should buy a box of each, so you can really get a better idea of the variations in color/pattern/knots.

MJ what did you go with?
