We're almost done remodeling our kitchen, but have gotten kind of stuck on the backsplash - any interior-design minded bees who can help me? We have white cabinets, oak floors, and a kind of white/taupe/neutral quartz countertop (see pictures below - sorry if they're huge!)

I kind of like the look of white subway tiles, but I think that's mainly because I can't imagine how to work color in - the rest of the kitchen is painted beige, but I'm not opposed to painting!

ETA: Added a close-up of counters as well
