What brick are you asking about? The house has painted brick now? Could you show a picture of the entire house?

It's a great house. These 'shed' houses look best to me monochromatic- I would paint everything (except the stone) Sherwin Williams Black Fox or Urbane Bronze. When you can afford it the deck handrails could use updating ( I would replace some sections with stadium stairs and others with glass). Otherwise punch up the landscaping a bit and you are good to go. The pine next to the house is so pretty, I don't love the cedar between the garage and the entrance, it looks like it is in the way?

Sage greens would be one choice nice with your roof color, or at least how it appears in your first photo. Soft white for the trim. Something like this Saybrook Sage (from Ben Moore) might be an option.
