What're your summers like, Nancita? What exposure does the porch have and what do you use it for? For our front, north-facing walk-in porch I chose a traditional Charleston green, a regional color which is almost black, for a deep, cool look that would harmonize with the lighter green foliage all around, but we were forced to go light on the porch we sit out on because the summer sun on even a medium green here will make it too hot to walk on. I noticed on browsing the web that current front porch floor colors are typically deplorably limited and boring, but I would think any color that was considered generally acceptable for a front door could be used in a somewhat muted or darkened, or perhaps lightened, version without raising eyebrows. For back deck color, you're outside but still separated from "nature" while sitting on it. Would you like a look that reinforces the shelter feeling (interior-style elements and colors carried outside), or would you like to embrace nature more and feel more as if you were sitting in a park or woods, only without your chairs sinking in? :)

I would go with charcoal gray or black.

thanks for the suggestions. I am starting to like the idea of a contrasting grey, either brighter or darker. BTW. here is my deck. A I don't mind to give it a quick sanding if required. I wonder if I should try to match the color of the round table (it is some kind of grey-brown)

I appreciate the advice, but I feel like I'm getting more and more confused (and panicked, as I have to make a decision by the end of the day). In putting the samples on the walls, BM Revere Pewter looks the best. It is darker than I had planned to go, but really looks best with the trim. I'm leaning towards going with that, but when I compare the chroma of Revere Pewter to the SW Creamy, it is actually pretty close (.98 to .91). So, is it not ok to use those colors together? Also, since the master bedroom has a door on it, I can go with a different color in there. Would it be ok to paint the walls the same color as the trim (SW Creamy)? I think it would brighten up the room, and look good with our rug and bedding.
