BORING there are literally 100s of colors of leather why only those 2 choices ? If you want help here we need to see the space and understand why either of those colors.

My choice is neither and I also question why you are limiting your choices to these colors.

I recently purchased two leather occasional chairs and I wanted blue to complement other furniture and design choices and there were FOUR shades of blue in the specific leather from the manufacturer. I say specific because there are different types of leather and leather manufacturers also differ in the range of colors and shades they offer.

The room the sofa will go into is very small and we need new tables/decor as well. We have stained concrete floors that are reddish. I wont be changing the floors for now as we have a senior dog that is blind and deaf and has a lot of accidents. My husband and I have different tastes, so because of that we usually wind up getting boring because its all we can agree on. I've suggested a navy blue and he looks at me like Im crazy.

IMO in a small space dark furniture is always a bad idea. Why not even a light taupe or a nice white cowhide that will stand up to anything. I have white cowhide sofas in my LR with 3 huge dogs and many parties over the last 15 yrs the sofas still look like new . BTW mne rarely have imagination for decor . They love browns and blacks and wood even when it is all wrong.

I like warmer leather colors so I would choose the bottom one -

To address your concern, my understanding is semi-aniline leather does have some pigment added to it. Which is not a bad thing, but if hides are pigmented in batches, hides from the next batch may not look just like the first batch. Just like fabric...you want to see a sample and order from that dye lot. Can you get a sample and order from it?

I have no problem with either one, except the style of it looks cumbersome for a small space.

This is a Smith Brothers sofa and it comes in three sizes. I like the style better for your room because it has sleeker arms and tight back cushions which I value in a small space. Just as comfortable, but not bulky looking.

Think about this color available...it is 11529-4431. I like because it's brighter than your two choices and, guessing at the red of your floors, I definitely like this one better. Ballard Design has this yummy linen wrapped coffee table. Something like it would be a nice change from black or white wood pieces. Brass floor lamps with trays, like this one, also from Ballard, will save space. Paint the walls B.M Palladian Blue.

I am rambling. I am home, down for the count, with long haul covid. Miserable thing. So, your dilemma was just what I needed to have some fun.

You nailed our floors. Thank you for the options. I’ll take a look at that color and the other options you gave. Hope you feel better soon!

1. @JudyG Designs This is a Mayo Leather we had been considering. What do you think of this? My husband refuses to get a tightback sofa.

Completely different style from your first two. The style, the color of the leather...love it! Great choice. It will fit, yes?
