I am thinking about Taupe cos currently that's one available on ebay.. I LOVE THAT COLOR! it shows more detail than a black color.. and i have too many white bag on the other hand ( Le fab and paddy). Might be taupe is a good choice!
I have both the Putty and the Black. Putty in real life doesn't really have any pink tone. It's very neutral beigish-grey color. It literally goes with any color you wear. I love them both, but for spring/summer Putty will be great! But then again, I love the black as well. If you care about the interior, I love going through the putty one, b/c the blue suede lining is lovely
