Congrats on the lovely new porch! :)

I'm admittedly terrible when it comes to exteriors, but I'm a little confused by the color palette here. I see: pale butter yellow siding, bright cherry red door (and some of it on the windows of the door, oh no!), white trim, light brown shutters, dark brown roof and gutters, red/brown porch and stairs, and brick. To me it seems like a lot of colors without a clear connection to one another. (The brick and porch work well together, though. Good choice!)

I would paint the trim around the door either dark brown to match the gutters, or bright white to match the window trim. I would paint the shutters either brown (to go with the roof/gutters), or red, to match the door. Also, you might consider a slightly darker shade of red - more brick-like and closer to the brick and porch color. (And then consider painting the shutters the same brick red.)

It seems like you love the red door, in which case, listen to no one! :) But if you are on the fence about it or curious about other options, this link will show you homes with yellow siding: http://www.houzz.com/photos/exterior/yellow-siding- (Many use white and/or black trim, but some use red shutters, green doors, etc.)
