Hi. I am renting an apartment where I am unable to make any alterations (no painting, wallpapering, etc.). There are large red and blue tiles and white tiles running along the wall just above the counters. They are mostly white, but there are 7 blue tiles that are driving me crazy because the only other colors in the kitchen are red and green.

I was wondering if there might be a way to cover the blue tiles with either green or some other color. It would have to be something temporary that could be removed when I move out.

Any ideas? Thanks!
