Grout, grout and grout?

I went to buy grout today and did not expect to have nearly as many choices there as in the tile aisle! I actually found a really helpful sales person (shocking!) who had a handy little sample board to help me decide on colors- who knew I'd have a different color grout for each of the different tiles!
I realized I hadn't posted pictures of our bath tile yet. I tried to get the colors right, but it's really difficult. The bigger tile is the bath floor (it's a textured beige and grey tile) and the smaller is the tub surround (which is white with grey marbling that didn't really show in the pictures). We're going with a mostly white and grey theme in the bathroom, but we wanted to warm the tones up a bit with the floor tile, which brings in some warmer, soft beige. Hopefully it will all work together!
