Need help with backsplash

Hi everyone! We are almost done with our kitchen remodel and I think I have decision fatigue and need some help from you all! I’ve attached a picture of our living room for reference of our style and the same finish that is on the fireplace will be what’s on our range hood. I am also not set on having the large photo above the sink so the backsplash doesn’t have to match that but I do love the happiness and color that photo brings to the kitchen. There will also be floating shelves on either side of the range hood and will wrap around the corner to connect with the other cabinet. I plan on putting more plants on them to bring in some greenery. My mom said she thought it’d be fun to do a colorful backsplash but I am worried to take a risk like that. Do any of the backsplashes in the pictures look good? Or should I keep looking? Ideally Id like them to run vertically and stack them right on top of each other for a more modern look but I am open to suggestions. Thank you guys! ♥️
