i'm sure you'll get a slew of "white subway tile" suggestions.
I like this one from Tilebar. Nabi Rocky Edge in gun metal. go over there and grab some samples. you get 5 for $5.
The Nabi line comes in this Arctic blue too. grab a sample of it also
I also like the soft blue color you have on the walls. Could do something like the blue?
These are from Heath Ceramics.
diff blue tones in a stacked horizontal or vertical layout
or you could do any other color.
these are both 2x10 tiles in more of a handmade look. this one has the mushroom tones:
grayish/taupe tile from Winchester. Dunwich, in a crackle glaze
since everything is solid, you could also opt for a diff shape tile
or take a subway and do a herringbone pattern.
there are thousands of options. could you narrow down the choices a bit??
