Yeah sorry. Could have been more specific
I'm leaning towards the Mirror I think, I'm colorblind so images are tough sometimes, should probably stick to blacks and browns, except the stitching.
I like the black outside with a lighter brown interior but I'm not sure which, was thinking walnut...
Although my painter brain is yelling at me to go for emerald or sapphire...
Oh! Emerald and Sapphire are GREAT. I love them paired with a brown leather. Here's what it looks like tabacco and Emerald on one of my wallets

We could go with 3 colors too 👀 they're would be an extra but anything is doable if money is there.

Alright. I'm going to hold off on ordering and DM you.
That emerald is 🔥

I never mixed black and walnut so I can't show you one of my wallets but here's one I found on Google. The pairing of those two colors would look like this. Looks very cool.

Imo I would go with a brown thread that matches the walnut so that the thread contrast on the black where it matters. But that's your call. If you prefer that the thread blend in more then black thread would be preferable.
Oh I like that, I'd prefer the thread pops a little to contrast the black, I'll leave the thread artisan's choice... Maybe that's where some color could come in 🤔, but a nice matching brown works too.
Black outside + brown/emerald or Saphir inside might be really nice.
If you could take a picture of those combinations if you have the leather on hand, that could be helpful.
I'm a fan of the colored inside. It might seem tacky but it's actually really nice.
