Your best bet is to take a bit of the yarn with you to your LYS or Hobby Lobby or Michaels and hold it up to other yarns. It would be much easier than to try to find a color online since colors on monitors aren't exactly precise.
Oh, does Lion Brand have another yarn in a similar color? You might try emailing them to see what they suggest; they know their yarns better than anyone, of course, and can probably suggest something for you.
Another possible solution is that you could use a lighter or darker pink yarn, or even yarn of a different color (purple, turquoise, cream, even brown or black), unless you really want an exact match.
