Your suggestions for gunmetal bags... for a wallet?

Since I change bags often I strive for neutrals that will go with any bag. I'd probably get a gorgeous black wallet then use black wristlets/skinnies to go with. Right now for summer I'm using a metallic gold wallet & other gold accessories in my lighter colored bags.
 
I'm going to go out on a limb with a color option. I have the Mia gunmetal maggie, and I use my berry penelope wallet here is the pic. It appears to go with all of my bags, but you have to like the color :biggrin:

The berry makes a nice contrast, maybe my pink poppy? I have the purple Kristin, but it was meh next to it.

I'm sure it would look nice! I love a pop of color with a handbag, escpecially if its not a bag with a color (black, brown, grey, tan, camel). It also makes it easy to find a wallet that is bright and fun in your bag.:P Take a pic and let us see.
