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.

Your white walls are too stark for your wood trim. Softer whites and other tints might warm up the room. Lots of Houzz discussion lately on best paint colors for rooms with wood trim. Here's a classic Houzz article about some great colors that work with wood trim like yours: https://www.houzz.com/magazine/11-terrific-paint-color-matches-for-wood-details-stsetivw-vs~9025200 Here's a Google link that comes up with the search: "paint colors for wood trim" http://www.google.com/images?client=safari&rls=en&q=best+paint+colors+wood+trim&oe=UTF-8&hl=en&sa=X&oi=image_result_group&ei=wtHIVPT-OcyYNtWehLAN&ved=0CC0QsAQ Additionally, like the others, add some lighter pillows to your couch--or a couple cozy throws--based on colors in your rug. A large round glass coffee table would showcase your beautiful rug as well. You could add accessories on the coffee table in colors from the rug. Yes, hanging plants in each window.

Here are some photos that may help you. You have the ceiling height to have a nice heavy rod just above the top of you window that could run the ceiling width. That will give you the space to draw curtains back to expose the entire window. I highly suggest that you work with a designer. A good designer has access to literally thousands of fabric choices and will be able to help you in selecting the perfect fabric and design for your room.

The potential yellowness discernible in Simply White is because it is actually a more colourful white from the Yellow Hue Family. That little kick of colour can work well on ceilings, as that plane can often make a colour appear a little darker & more greyed anyway. So sometimes a choice of more neutral greys here have a possibility of ending up a little grey & shadowy. This is obviously dependent on the available light. Chantilly Lace is a more neutral white from the Green Yellow Hue Family. In character in balanced light it can appear ‘just white’, but in some light people see a hint of its inherent greenness, some might even read it as blueness. Again depending upon how well balanced the available light is. Super White OC-152 is that bit more neutral & so could read a touch more crisp again. Many people prefer a more neutral, crisp trim. It can give you more options for alternative wall colours, should you decide to repaint down the line. Neither Simply or your trim choice would be sat next to each other though, as the wall would come between them. I think the biggest concern would be sitting Simply White next to Classic gray for the reasons mentioned before. If you are set upon Classic Gray then I would repaint the ceiling and swap to one of the more neutral options. I would shortlist your line-up and sample upon board or lining paper in your space so you can move them around.
