The dark grey paint color was a custom match to the metal roofing we used, so unfortunately there isn't a color name. The metal roofing color is "Burnished Slate" (a pretty universal color in metal roofing). The red barnwood is Cabot Semi Transparent Baked Brick. This was applied to old, weathered wood, so applying the same color to new wood might result in a brighter color. It's always best to try a few samples first. Thanks for the comment!

Shingle color?

Shingle color is Weathered Wood.
