Looks like the chimney is dark gray. with the cedar colored roof, I would paint the house and stonework appendages to match the chimney and do the garage door, gable and front door in cedar.

Chim/wood is a dark brown-gray? Paint the same.

Your roof is pretty brown, which means you're going to have to be careful about which shade of gray you use. After finding the right shade, then think about the front door, but I think you're right, pink will not work with the roof. How about green or yellow?

A turquoise door would work
