Hello - a front door is always such a wonderful opportunity to take a risk. Keeping in line with your classic home however, you'll want to be conscious of the level at which you take that risk, so with that in mind, I see a lovely intense version of an inky blue. Your shutters should take cue from your door as should your steps up to the house. Take a look at this beautiful Martha Stewart color (Ink MS8318), it would look wonderful.
