hermustangs, if you'll read the "new to GW" thread below on this page (or if it's left this page by the time you read this, search for it) you'll find explicit instructions on how to post photos; very easy to do. I think you'll get many more responses if you include photos. I'm not good enough with colors personally to try to answer your questions without seeing the rooms. Good luck!

I had a similar situation in my kitchen with a dark golden brown countertop and a Silgranit sink. I went with the Cafe Brown color even though nothing else in my kitchen was brown and the trim was all white because the sink blended with the counters better. I love it. I think you'd be really happy with the black for that reason. Also, my dark sink really does hide stains, discoloration, etc. I almost fear ever returning to a white sink!

Choose your trim and door color to go with the floor first, wall color second priority. What color is the floor?

It's not the kind of porch that is conducive to having a lot of planting in front of it. It needs a broad landing itself and a nice wide walk to it. The walk should stay at least 6' away, min,, from the house in order to leave sufficient room for foundation plantings. "Dark grey with white trim" sounds harsh to me.I like house colors in the medium grey/taupe range with white trim. They can have a tint of color so long as it is not too powerful. The fourth example down is nearly a reversal with the body being the light color and the trim darker, but I think it works well, the house being light grey, not white.
