I just think it needs more bright white trim around the windows and the fence painted also white. Going round to the back addition, I would paint the timber boards the color of the stucco, trim white and get some great deck furniture and lighting.

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.

Hebel is preferable.

Personally , I think the main colour is fine , the crisp white on the poles and most of the terrace is fine -- the two different 'sandy khahki' shades ( the window surrounds , and the planter ) looks out of date . I'd do both of them in charcoal , as well as the terrace base board and the upstairs downpipes . It looks like the barge board and the veranda are already a charcoal -- if not , then darken them up too . The mid grey on the steps etc is fine as is , it's hard to see in the photos but the front door looks like it might be a nice solid wooden one -- again , thats fine to me , but I'd do the door surround in a crisp white to make it more noticeable . The other brighter option would be to do the window surrounds , the door surround , the top barge board including the gables , the terrace base and probably the terrace top rail -- all in a bright sunshine yellow !
