The lighter one is not good. Luckily there is only about 80 pieces of this. For the correct tone which is a better match but not exactly but still acceptable there is 4300 pieces in stock.
If the close matching bullnose is still not acceptable, another option is to use an outside service that can exactly match a tile. However the pattern will not go over the curved edge of the bullnose. A color glaze will closely match the tile. (pic below)
