I love your outside entertaining area. It does need a color that would complement but give the area a focal point. I like the darker red,orange colors you may find in natural. You could dress up the table with accessories and place cushions in a complimentary color on the benches. Colored potting containers would also bring it all together. I like the uplighting here in the photo you could place along the back fence to add drama. Your area reminds me of Modern mediterranean landscaping.

For the fireplace inserts go ahead and do the green order a second set of panels that you store that are more neutral. In 10 years or five years you may not like the green anymore. It's possible you won't have access to different colored panels at that time. As for the color I like the ideas of going into those silvers it would coordinate very well with your blue couch and it will pull the blues out of the curtain panels. For the wall coloring use the warm golden color in the drape. There is one piece of the flower that has this color and it will balance the weight of a dark couch. If your room is small don't go too dark in this color. You could use it on the main wall and pick two shades lighter on the other three walls.

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.
