What color yarn would i buy if i'm looking for tiffany blue?

my friend says she's using the color tiffany blue for her baby's nursery but i don't know what yarn color i'm looking for and what the yarn maker would call it. I mostly use red heart brand yarn.|||It's not a perfect match, but http://www.shopcaron.com/Simply-Softreg-鈥?/a> has a good color approximating Tiffany Blue (called blue mint, just in case the link doesn't take you directly to the color for some reason). Caron Simply Soft is my favorite balled yarn, incredibly soft, it steams perfectly flat and washes well, and isn't totally expensive.|||Tiffany Blue means the color of the gift boxes that the jewelry store Tiffany's uses. Here's a link to their homepage so you can see the exact color she is talking about. It looks like Robin's Egg Blue.|||it's a really pretty light almost aqua-marine-ish color, like this link's pic: http://www.housefabric.com/ProductDetail.asp?ProductID=5511
