I would recommend a soft gray...see photo below...

Yes they do have similar styles in porcelain, but to me it doesn't look the same. Search around that site and see if any of the other tile designs in other materials strike your fancy. I know you said you don't like the subway, but you could get a glass tile in a 2X8 and lay it in a herringbone or find shorter ones and do a chevron. Don't know if you care for mosaics, or penny rounds, those would also look nice. You are going to have to narrow it down to a look you are drawn to, and then go from there. Search kitchen backsplashes on here to get some ideas as well.

It’s is back painted glass. As a back splash it can be used as it’s easy to clean and maintain. Highly recommended to be toughened. The entire back needs to be cladded in waterproof plywood and then the glass is stuck on to it with special adhesive or silicon gel. Any reservations on using plywood then you can opt for WPC ( wood plastic composite ) which is alternative to play and is totally termite-water proof.

I wanted to use a shimmery pearl backsplash but it was problematic to install. Looking for something reflective. My island is deep blue (sea serpent by Sherwin-Williams), cabinets white with clear glass in second row uppers, fixtures, pulls and knobs all champagne bronze. Hoped to find something more exciting than white subway but I need help and fast so we can install the range hood and the stove!
