We are looking at this ceramic tile for flooring. However, on the sample board, the color does not seem to go all the way to the tile edge leaving a whitish edge all the way around the tile. Is this common among ceramic tiles or possibly just unique to the tile on the sample board? Should we be leary of this and that the ordered tiles would all come in colored in this manner. I don't think grouting would disguise it as we would be using a darker grout.
