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. Explore Google Images as there are all sorts of house paint combinations.

We are wanting to paint the side on our house but leave the brick as is for economical reasons. I am stumped on what colors to choose that will also compliment the brown brick and roof. I am wanting to do a darker siding color and a light trim color. Any suggestions would be greatly appreciate!!

I'd prob paint the stucco a soft creamy and do a dark trim. (did you have the pressure on too high? did it damage the stucco? if so, you'll have to get it patched before painting. not too sure about those shutters. they look too small. if you must use them, they and get more authentic looking ones for a spanish style look Try Shoji White and Urbane Bronze (SW) dig away the grass against the foundation and do some flower beds. see this flower bed? notice the brick and shutters are almost the same as yours. look at what the flower bed like this does for the look of the house. just dig out the grass agains the house and thrown down some dark mulch and a few shrubs Spruce up the landscaping and whatever paint color you choose will be a huge improvement. Paint alone isn't going to fix the curb appeal. get a colorful ceramic pot w/a nice plant and place it under the light plants w/these colors would look nice w/the brick bring in an address plaque something like either of these. or do some vertical numbers on the right side of the door here are some other creamy whites and darker trim colors. grab some samples. Some other combos of colors if you want to use the red w/the white/dark trim color. Your landscaping (or lack of it) plays a huge role in the overall look. get some flowerbeds/plants of some type. for the side of the house, do something low maintenance like the pebbles and cement path, and the simple plants grown along the side of the house
