There are 14 teal-aqua-peacock swatches on the color card I have. Odds are you will never find a perfect match even if you knew the color number because the dye lots can be quite different colors...even more so now that Patrick Lose is no longer at Moda. Good luck to you!
I suggest you go through the swatches at either Hancock's of Paducah or Craft Connection (they both have almost all colors) to see if you can find something close.
