Seems a shame to paint that brick. Maybe one of the photoshop gurus can do a mockup for you of some color options. I'm no expert, but this seems craftsman-esque, which are always so rich in color and contrast. Good luck with your decision.

Can you show us a picture of the roof color? Are you interested in possibly removing the awning? I think a pretty mid-tone blue (what shade exactly would depend on the color of the roof) would look pretty, with white trim. For your door, I would consider a navy though I kind of like the way it looks now with the white.

Your home is BEAUTIFUL inside! What a wonderful job you have done with it! I love the old wooden floors, the crisp white trim, and your modern furnishings. It is lovely. You have done a great job with it. I like the beige/gray walls inside, as well as the gray tones that you have used. Your home could look wonderful painted a blue/gray color, if you want a change. You could experiment with some color on your porch with large black modern style pots filled with colorful flowers. Your yard, as I see it, is mostly paved. So, if you want to bring color there, too, a planter under your front window (with the awning) would be nice. Trust your judgment AND taste. You have both!

I wouldn't paint that brick. Lime wash is (mostly) for unfortunately colored brick. Yours already has a similar lime wash look and it has a really good colorway. Get a designer to suggest some new ideas for the trim/shutter/door color. Try taking off the shutters to see if that helps give an updated look/feel.
