Hi again- I have been looking at Benjamin Moores colors and have chosen a few you might look at. My technique for color choices is to buy several large sheets of MDF from the hardware and several paint samples that I think will work. Grab a plain white sample pot as well and just play with colors; if what you thought looked good in the shop and doesn't look good in reality, just add a bit of the white to lighten it and use the darker tones to deepen. Once you've found the color you like paint it on one of the large MDF sheets and live with it for a day or two and see how it looks morning,night, south side of building,northside of building. If the color that you like is one that you've mixed yourself, just go back to the paintshop as I'm sure B Moore would have the right shade so you can match it. Do you know the color name of the roofing? Is it IRONSTONE or MONUMENT? I'd be tempted to use that same color for the windows. My personal trick for contrast and trims is to take the main color and ask paint shop to make it up in 1/4 strength even lighter if need be. Good luck and post pictures when it's finished.

Hi, I know there are so many things to take into account and it's hard to get perspective from a photo. The white you can see is an extension with building paper, and the red is the existing building which is two story. The exterior is wide weatherboard planking, the windows are silver aluminium with very little trim. The doors in the front of the picture are French doors from bedrooms that will open to an enclosed courtyard ( yet to be built of course) The roof will be a light grey/brown but you won't see it much because of the flat roof style. There will be decking and ballustrades covering half of the new extension.

I would like a warm mushroomy gray with darker brown/charcoal for the trim and window framing. Also, trim the bushes out front so we can see where the front door is...

If you want an all black look it can work, depending on the style of your house and your location.
