I love red doors on a colonial.

i love the red too, but there are a lot of gray houses on my street with different shades of red. my sister lives directly across the street from me and she has a red door. but thank you for your input. what do you think about black door with black shutters.

What about burnt orange or blue?

I think I'd be tempted to go with a navy front door. It would compliment the gray and white nicely.
