Any suggestions would be appreciated!

I am a big fan of using 3 colors on exteriors of homes. It is hard to tell from your picture, but I am assuming the sashes on your windows are white (one color) I would use the light tone and darker tone of your stone work for my other two colors. The trim around your windows (frames) could be painted the darker tone, and the body of the house the lighter color. The post and rails of the front porch the same color as the window frames. I love using the complement of the house colors for the front door. This color would most likely be in the blue to green range of color. The down drains I would paint the wall color of the house. (Your roof is a nice color for the color suggestions I made above.)

It looks like it's all maintenance free siding and windows so I would try the shutters, window box and step colors 1st before adding more maintenance to the home. Even just the front siding could be painted and leave the rest white. The windows would be more up keep to have to keep painting. I love white trim on 99% of homes.

Unfortunately, the window (sashes) are white and cannot be changed. Everything else is up for grabs. There are several young shrubs, but it's winter in this photograph (so they are barely visible).
Thanks for the ideas, everyone!
Thanks for the input, everyone!

Beautiful home - the brick seems to be rather golden, perhaps with rust tones. The roof too is a warm tone, so with the white window sashes, the trim wants to be a more neutral tan to bridge the eye to the pop of white, while the body wants to be a warm neutral - like camel. Look at http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW2828-colonial-revival-tan/ and test the trim in this tone - http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW2835-craftsman-brown/

Now, against all the tan camel rust, I really love a blue door, as noted above it will complement the rust tones - test http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW2864-stratford-blue/ - you want a blue with a touch of green to make it unique.

Hope this is helpful - when you get specific color suggestions, of course, you must test them in your light - I picked a stand in color for your brick tones based on this photo, but you will want to select a camel that has the same undertone - not too red or orange or yellow.

Is your door a stained wood? I think a rusty orange would be nice to add as a accent color or a teal /Verdi color finish. Or a taupe for the siding color.
