HELP! I need a Renter-Safe way to cover ugly kitchen wall tiles!

We currently rent a "mostly" updated house in Tokyo, Japan. However, the kitchen has this horrible beige tile with pictures spaced randomly on tiles throughout. Since it is a Memorial Kitchen honoring the original owner's wife, we are not allowed to make permanent changes, but contact paper will show the grout lines.

P.S. The color beige is like nails on a chalkboard for me!! Even when perfectly clean, it makes my kitchen look dingy!!!

Ahhh the life of Military and Civilian renters overseas!
