You could also bring in some texture with bamboo sticks or decorative branches and help balance a bit the height of your room with small scale furniture. Spray paint them if you find the perfect size and shape but they aren't the color that you need. Ikea carries white decorative stalks for a very good price. the ones in the 1st picture hold well with small kids around and you don't need a vase for them. there are washi paper or crinkly paper floor lamps with a soft beautifully diffused glow For a budget friendly version check ikea or target http://www.ikea.com/us/en/catalog/products/80028552/

Dear Crazyjunglite, please let me add some ideas for your space. I beleive that a nice combination of two curtains like the one with the blue and peach double curtains in the picture, will give you an eclectic feeling that matches to your painting. The combination of colors that I suggest is this blue with brown flares and the cream-peach taffetas, and the soft cream sheer behind. It will join all the rest beautiful items suggested by now: https://www.etsy.com/listing/163787105/blue-curtain-polyester-fabric-122-inches?ref=shop_home_active https://www.etsy.com/listing/163785041/light-yellow-beige-curtain-polyester?ref=related-6 https://www.etsy.com/listing/167660815/35-discount-for-one-pair-of-two-beige?ref=listing-shop-header-1 https://www.etsy.com/listing/167363693/ecru-sheer-curtains-fabric-118-inches?ref=shop_home_active

I'm not against colorful homes. There's bright, and then there's too bright. I wouldn't go with persimmon for the whole house. The photo you provided has lots of white trim which offsets the orange, but your house doesn't have that much trim (unless you were planning on adding some, which I think would look good no matter what color you ultimately choose, but even so, I wouldn't go with persimmon for the whole house, as it's still too bright). To repeat what @nwduck said, the other homes in the neighborhood don't appear to all be done in the bright colors, and so yours would stand out too too much. I like @deco's idea of the bright door, if you really love a bright color. For the rest of the house, any more subdued color would be fine, along with additional trim around the windows, and assuming that your siding color coordinates with your roofing color.

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.
