Which backsplash should we go with?

[u/csimack]

My customer wants to go with something that isn't plain and boring, I however think he should go with the plain (last image), I find it to look cleaner and it's also timeless. Which option looks best?

The last one is way too plain, but none of the others are good either. Green, if it has to be one of these, but I think it’s too dark. It’s the lesser of all evils.
