we have an old American Standard toilet in a blue shade, it needs to be replaced and we would like the same color. The numbers inside the Tank is 4049 L71 and the numbers on the bowl are 9671L7. We think these are probably Dresden Blue or Regency. Also I have a peachy-colored Crane-Drexel toilet, same issue. The numbers inside that tank is 95376 Pat. 2334855 and think this one might be candlelyght? Please help, the new ones have to match the sink and tubs that are in these bathrooms.
