Exterior Paint & Roof Color Choices

[Blake C.]

I am doing a pretty big remodel project. Currently the house has a typical 1950's wood lap siding. It is getting a new roof, and full exterior paint job including trim. I want to keep the colors of paint and singles very common and timeless as possible to attract tenants and allow for good resale when the time comes. Does anyone have suggestions? 

Im thinking Dark Charcoal/black roof, white trim and _________ as at the main color. The house next door is grey and white.
