If your siding and trim are both true white, you could make your roof any color. To stay with the classic farm look, do keep the trim true white -- and not the glossy variety.

My house has white vinyl siding, and it requires constant maintenance in terms of cleaning. We live in the country (we're farmers), and the white shows everything - especially cobwebs, dead (and live!) insects, and dust from the road and surrounding fields. It is especially bad around my entrances and windows (probably because that's where I see it close up). We power wash the house in the spring and fall, and I constantly clean my entrances by hand so that it looks respectable. The house we are building will have darker wood siding and a grey metal roof. I have no doubt that the darker siding will also get dirty, however I think it probably won't show up as much as it does on the white siding.

Why oh why do people insist on taking pictures with the house shaded, then request opinions on color? Take the picture when the sun is at your back and the front of the house is in natural light. And yes to a nice, soft sage green. It’s lovely in a wooded setting, and if the house tends to get mold, it will be much less obvious. Lovely house!

"The trim is all PVC white. Do you think an ivory or light tan mixed with such bright white trim would look okay?" It would be perfect for this style house. And use horizontal siding and paint it all ther same color.
