What a fantastic architecture. When you do the brick, if you stain it with masonry /concrete stain you won't have the same issues of maintenance as with paint. They will spray it evenly - through you will have to select a deeper color - either taupe (brown-gray) or a straight charcoal. Love your windows and the classic angled railing. I think a dark gray on the siding will make the orange brick jump even more. What bothers me is the white (railing, fascia, eaves) juxtaposed with the earth toned stuff. So I would recommend camel tones - for the siding - something like http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6108-latte/ and the hopsack next darker tone for the garage door. Use the lighter tan for trim that is now white - http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6107-nomadic-desert/ Use the darkest tone if you are painting concrete steps. If you think you will stain your brick charcoal, then the white eaves and trim are probably right, and you may not want to paint it tan now and then go back. If your brick were charcoal, then I would block out the rest in grays and blue grays - leave the white eaves, but take the railing and posts charcoal too. A blue gray door - like sw smoky blue.

Do you have any photos of the front of the house that may give us a better view of the green trim? Have to say that painting costs so much and lasts just so long, you may want to wait until it's needed.

The setting is quite tropical, so a darker scheme with white trims has such a tropical holiday feel. You may consider using a concrete face brick for the lower section. This will be modern, and eliminate the need for painting, while still creating contrast with the upper level. Try a colour for the main house like Resene Evolution, or Quarter Evolution, both would be perfect for your style of home. The colour scheme that we recommend for you is our Rainforest Board which includes everything you need to bring the look together! https://www.bodoboards.com.au/collections/paint-concept/products/rainforest-paint-concept We would love to see updates as you go.. its going to be great!

Oh wow, it looks fantastic! The black looks so striking against the white, not too sharp at all. Congratulations on the house, you must be very excited to move in. :)
