Hello,

I would be happy to help. I did find a home on Houzz.com with a reference to Chocolate Brown Alcoa. Is this the home that you saw? http://www.houzz.com/photos/425218/Salem-Avenue-Renovation-traditional-exterior-minneapolis

From what I could gather, the "chocolate brown Alcoa" was in reference to the pre-painted Alcoa metal trim and gutters, and was not an exact color name. A possible match for the dark brown color could be: http://www.myperfectcolor.com/en/color/75122_Alcoa-Musket-Brown

The siding on the home is reported to be Benjamin Moore Copley Gray, http://www.myperfectcolor.com/en/color/102867_Benjamin-Moore-HC-104-Copley-Gray and the light trim is Benjamin Moore Elephant Tusk http://www.myperfectcolor.com/en/color/103062_Benjamin-Moore-OC-8-Elephant-Tusk

The home is one of the most popular ones on Houzz.com - the color scheme is gorgeous.

Hope this information is helpful.

Diana

thanks so much that is exactly what I needed.
