It does look a bit more gray but it still has brown tones to it in natural light. The pic quality isn't that good since I was in a darker room

And I already returned the dark dune. BUT I do have my
Coach bag which I compared to the dark dune soft leather and the color was identical. So I will take a better picture tomorrow with my dark khaki and my Coach bag ("dark dune") lol.
Here's a better pic of dark dune soft leather, it's pretty true to color here
Dark dune is very classy as well but it's a bit more "muted" as a color, while dark khaki has that true khaki tone with slight yellow undertone not gray. Both are soo pretty! I also like luggage, it would look amazing in soft leather as well. Hard choice!
