Floored by Choices

Because my farm home has white carpet in the hall and light beige carpet in the den (I didn't choose these colors—they were here before we bought the place),  I'm going to have the entrances to each room tiled. I figure the mud clean-up will be much easier with tile.

Now, my problem is which tile. I went to Lowes and looked around. I found three (relatively cheap) possibilities. Here they are in the den, where the final choice will be in front of the sliding glass door:

Which looks best with the carpet? The dark tile coordinates well, the medium tile is close to a match with the kitchen counters, and the light tile brightens up the place a bit.

Now, here they are in the hall, where the area just inside the front door will be tiled:

I don't think the dark tile looks good here. Check them out against the wall:

I think I can eliminate the dark tile. But do I go for the light one or the medium?

Too many choices, even if it's only two.
