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.

I'm a Certified installer for Trex decking. Trex Transcend is encapsulated board, with a finish that resists staining, scratches, mold and has a high definition wood grain surface. I don't know what you did to it or whoever worked on your house did something to it, but Transcend decking does not need staining or painting and the protective shell protects decking against fading. Trex Transcend and a few other Trex decking products like Trex Enhance, and Trex Select, they cannot be painted or stained. The only thing can be painted is Trex Transcend White Railings and you should only use light color paint. If you use dark colors, it will absorb heat and it will damage the surface and you can kiss your railings good bye. Also high quality fast drying primer should be used and you have to use Oil or Water based exterior paint and most importantly surface prep is the the key. When it comes to painting specialty surfaces like Trex Railings, hire a Pro to do the work. With that said, if you installed Trex yourself, you have to go to the store and have a Trex representative come out and check your deck. They will determine if loss of color fading was due because of negligence or not. If its a material defect, they will cover the material cost. If you had a Certified contractor do the work, they will cover material and labor. Call your contractor and he will get a Trex Rep to come out within a few days. Good luck

OSB board will do the trick. You need another photo for us to offer a species and finish. Natural finish (clear coat...water based polyurethane finish...NO oil modified) in a low gloss or satin finish on white oak with FLOOD LIGHTS will offer the same "look" as the poor photo. Beyond that, you will need a better photo.

Your drapes look like they're fine. It's hard to see if they're long enough--do they just touch the floor? That would be the right length. Make sure the paint you pick blends with the color of the drapes and the two chairs. The Edgecomb Gray looks like it would work or you could go with an entirely different color and add pictures and rug to pull it all together. Love the color Sea Salt by SW.
