Here is a picture comparing the neo noe in galet and the zippy coin purse in turtledove (tourterelle).
I agree that turtledove is warmer and a bit darker as well. It could also be because of the epi leather that gives the galet a little shine so it appears lighter.
In terms of empreinte vs epi, I think empreinte is probably more durable but it’s also softer so it will likely stretch a bit more than epi. The epi leather is stiffer when I touch it so I don’t think it will stretch as much.
But in all honesty, both colours and leathers are beautiful so it really comes down to preference.
In general, I prefer empreinte leather more and I like the galet colour a tiny bit more.
Hope this helps!
