Sunset Falls Beige wall tile does not match Sunset Falls Beige floor tile

We are in the middle of a bathroom renovation. The tile I picked out arrived and not only did the 12x24 not match my sample (it had a lot more grain in it and the color was off) but the wall tile is much darker than the floor tile. It has a ton of grain and I absolutely hate it. It is already on the walls, looking like cinderblocks instead of the lovely neutral I envisioned. There is nothing like spending $20 on a project to be horribly disappointed. The wall tile, 4x12 and 6x18 are both made of ceramic with a white base and image painted on the surface making it much darker than the porcelain floor tile which has a grey base. The requirement for a 6x18 grout line makes this all the more look like a castle wall. I also wanted to note that the 12x24 floor tiles are not able to be laid in any pattern that requires two vertical tiles to abut a horizontal one such as a basketweave pattern. The required grout line makes the two verticals extend over the sides of the horizontal by 1/8 of an inch and therefore are unable to be lined up in any pattern. This was incredibly disappointing to me and I wish I had known before purchasing. I never would have selected this tile.
