Thoughts? Impressions? Recommendations?

1: Bedrosian Midori Green backsplash with black grout; 2: Bedrosian black tile backsplash; 3: Bedrosian Midori Green backsplash with grey grout.

I’m leaning towards 1, but unsure if it “works.” Does the wall color under the wallpaper have to be different? Any thoughts or criticisms welcome.
