Any color found in nature in large amounts (brown, tan, etc) Usually those colors are selected to blend the house into the surrounding woods. IMHO anyway :)

Red. A darker red or a dark red brown.

Thank you for the suggestions. The cabin is on the waterfront on a small island. I find the green roof is limiting when considering the exterior. Their will be an addition with large windows that are white trimmed. The planning process is daunting but exciting.
