It's refreshing to see nautical, navy BLUE. Everyone is saying the same thing for the most part - just introduce another color, definitely bright (yellow or orange IMO) and it will make it more current. What I really like is how your style will withstand the test of time - and with minor updates now and then it will always look fresh and "current".

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.

HI --- Why is the yard paved , it looks so barren ? The color "Willow " by Benjamin Moore Paints would work with what you have . I am not a fan of the roof color ... if you change that , you could go with a textured dark brown or go to a textured charcoal or a grey . Maybe make the front door stand out more with a color ... maybe a rich dark green or a Navy like "Polo". But this house would look wonderful with a veranda /deck/porch from the front door to the opening just in front of the last window on the right ,in the color like the windows and trim . For the landscaping .. if your keeping the paving I would say get some big planter boxes . I would remove some of that paving because the house could use some trees etc. If so then I would plant a cut leaf weeping birch just left front of the window but mature tree spread away -about 20 feet. Also see if that down spout can be moved to come off the side ,instead of on the front . And add some exterior lighting to accent the house .

Blue gray window frames match the funky roof. The cedar is diametrically opposite on the color wheel as a orange tone. Usually the browner grays (sort of the light shade now on the stucco) do better with cedar to say modern, but since you have the blue gray, allow me to suggest that you just go as dark gray as you can - nearly charcoal on all the weatherboard. If you are in a high heat area (palms might or might not be - that might be the ocean on the horizon which might me an onshore breeze all the time) then you want a white. Not a blue-white but a warm white - bm maritime white is a good choice. With the cedar and the two blue-blue-gray elements, you need neutral without tone.
