IF this type of very grayish taupe color really floats your boat, they were quite different. But they're different the way different reds are different, so it's more a matter of degree than "Wow two totally different colors". I think VGR2 will be more flattering on medium skin tones than Icon, but pale and dark skin tones could pull either off equally. If this is a weird color to you or if frosts are hard for you to stomach, you might hate them both! I guess if anyone is getting one out of curiosity, it's better to get VGR2, because it goes to a good cause, whether you actually wind up using it or not.
I'm getting both, but I can rock these colors - I'll wear Icon for more daytime things and VGR2 for dressier situations. It's like having two related colors instead of one with a BU.
