I just got my BI City today! It's not exactly like any of the pictures I've seen posted here. And rather unlike the one posted above. But I LOVE IT. It's a rich, deep, turquoisey teal. Vibrant without being bright. Definitely deeper and darker than I had expected, based on most of the pictures I've seen. It is like a deep aqua, tropical ocean color.
The amazing thing about this color is it is VERY chameleon-like! In some lighting, I swear it's got green in it. In others, it's like pure turquoise. Strangely with mine, I don't see any grey. It's gorgeous and I'm sooo happy!
