Wow- great house! Here's a Benjamin Moore color scheme that will bring out the best details for you:
1. Painting the front door (including threshold and trim) and all window trim a deep greenish black to emphasize the stone detail and complement the brick. I like Benjamin Moore 1582 Deep River.
2. Paint the porch columns, frieze shingles, and pilasters on the gable in a warm gray like 1529 Sting Ray.
3. Paint all other trim OC-9 Ballet White
4. Paint the porch 1537
5. Paint the porch ceiling a surprising 709 Heavenly Blue
This may sound like a lot of colors, but they are mostly neutral and blend with each other to show off the architecture in a sophisticated way and also bring out the warmth of the brick and stone. I'd also like to see you replace the porch light with a classic star light like this one from www.mydanilo.com ( http://www.mydanilo.com/glass-star-lights/frosted-glass-star-light-bronze-frame-16 )

You'll have to send AFTER photos of this one. I'm really excited to see how it turns out!
