paint it gray with white or mossy green with cream trim

Personally, I would go the modern route and paint the siding white, a new front door with a pop of color would look great as well. I'm not sure if you're willing to eliminate some of your bushes, but in keeping with the retro/modern aesthetic of the house you could introduce a more geometric clean cut type of landscaping (see photos attached). Also, you could radiate some stepping stones in a geometric pattern where the snow is to create a more welcoming front entry. An array of potted plants in different scales would look nice in the niche by your front entry and to the right of the front door (especially for when the weather gets warm).

I LOVE this modern house. I'd go with gray - and have a rock garden with topiaries. Maybe a pergola front porch? Here is a quick (very rough) look with a soft gray. Not sure what color I'd paint the trim.

Great feedback all. For now we're fixing the roof, facia, soffit, mechanicals. Then the creative work begins. I'll post final photos in a few weeks.
