I totally get where you're coming from! There was a time when almost all my bags were black. Then I discovered color and started feeling black was too stark for me. I'm now down to 3 black bags and my favorite is the Lanvin Amalia MM.
I actually purchased a black Chanel classic jumbo flap in caviar ages ago and also a black Balenciaga twiggy in my quest for THE perfect black bag but realized neither was perfect for me (I prefer the Jumbo in lambskin and in other colors and decided the Twiggy was not the shape for me). I prefer the Giant Covered Metro to the Twiggy, and though I think it looks awesome in color (I have it in Raisin), it looks great in black as well.
Here's a picture of the Amalia taken from blogspot. And a Metro in Galet taken from wellthatsjustme.blogspot (I believe these photos are also posted in the Bal forum)
