i'd pick the medium charcoal but not until the samples observed in my setting. the discrepancy under the different settings shown is significant. Have the samples been placed in your home?

I like the lighter brown color. And second herbflavors advice on making sure it looks right in your space

I would go with the more natural looking wood stain (brown).

Our home will have a large windows in the kitchen and dining so we’ll get something closer to the first picture for most of the day! @herbflavor
