K.D.
If I were you I would drive around new subdivisions and see what catches your eye. We are currently building a house but I probably chose colors that would scare other people (I am an interior designer, so I am a little more brave!) We are doing a taupe vertical siding with a rock wainscot, harbor blue horizontal siding in the eaves, cream colored trim and copper colored metal roofing as accent above the porch only. The rest of the roof will be black with just a little brown. If your house has some rock or something you may want to just take your colors out of that. I personally think a lighter color trim with a darker color on the main part of the house looks much more up to date than light with dark trim. Good luck!
