i agree with lighting trends on the peach ,here are a couple of palettes to choose from note your lighting will accentuate the mood and can give the hue you want , but definitely go for a neutral , the colours are from sherwin williams, benjamin moore , behr , and kelly moore

Thanks! I was also leaning to leaving the short wall alone but wanted some outside advice :) appreciate the opinions!

Bet your farmhouse kitchen is cheerful and delightful! I'm curious what colors you have in the adjacent living room. Are there any fabrics or unique accent items you'd like to have more attention? Feel free to bring a pillow or quilt or pottery piece from the living room to your yellow tile to get a feel for what color might capture your heart. Will it be a mellow, blend-in kind of look? Or something that adds a "pop" to your rooms? Cant wait to hear your discoveries!

If you love the marble tile, go for it! You can always buy a stainless or white range hood backsplash like this http://www.wayfair.com/Air-King-Range-Hood-Back-Splash-SP2430-AXK1174.html to slip in place when you are cooking something really messy. I have a travertine backsplash and use a stainless sheet when frying. It works great and no worries about stains ruining the stone.
