When you say exterior architectural details do you mean like gingerbread trim? My mind is going to Victorian style. If it's Victorian you could use several colors on the trim to highlight different features. I think SW has brochures that show different combinations. The gray/white/black sounds nice, sedate and tasteful. Not really my style - I'd be inclined to get whimsical with the third color. What's your favorite color? Bright blue doors in Jamaica are traditional to ward away evil spirits. Red would be very nice. I have an oval window in my staircase - at times it's matched the trim [boring] been bright yellow [neighbors liked that] and currently it's blue. If it's just small areas I'd go buy a couple quarts of paint and play around.

Well...long story... Hubs is a do it yourselfer and has big plans for the front entrance in the future. Right now we have the original shrubs bordering the walk to the front door with an evergreen tallshrub that is tall by the L shaped entrance we now have. Our plans are to extend the slab the length across the front of the house and then tile the entire front entrance to match what we put in the house and on the porch. We already have the tile. Then where we have wood and shutters, we want to put a stone type finish. Probably grayish in color, which is why I mentioned the gray color for the trim etc. The overhangs and soffits are vinyl, not wood so even though they could be painted, it would not be easy to do so. We have a big island in the front of the house with two big oaks. The back porch is open to the pool area. There is an indoor garden area with large tropical type plants (?) and caladiums for the summer. In winter I have potted impatiens in there. We have alot of work to do on the porch ceiling. We had a leak on that part of the flat roof so it was repaired but the ceiling needs patching and painting and the walls of the porch need painting. This used to be an enclosed porch before we bought the house and put up the pool enclosure. We removed the screen part of the porch and all that but had to leave the posts for ceiling support. Turns out they weren't really anchored in the flooring so before we had the tiled installed, hubs fixed them and now they are anchored properly and he made the white decorative parts to cover over where he had to do the repairs. This will all take quite a while to do - but choosing the third color needs to be done now so that when it is time to do the front, it will match what is on the porch now. Repainting just to match colors isn't a priority as far as Hubs is concerned and painting is not my forte'. I will come back with pics as soon as I can get them taken and posted. I know it will help to see what I am saying!

Well, just to clarify... I didn't say just the camera...the OP only partially quoted me in his/her response making my opinion appear all about the camera. I said... "I think a lot of people could have taken those especially if they had your camera, a great backdrop, and pulled the 4 best pictures from the 100 pictures they took". There's a lot more to that then just the camera...

What is in these rooms? What color is your upholstered furniture? Your curtains? Your rug? These things should come before your wall color! FAR easier to find a paint to go with your furniture/curtains than to find furniture/curtains to go with your paint!
