Now it's beginning to work! Luv the rug! A few more red showstoppers, and I luv the post about matting your family pic, and larger frame for it. Looks like you might be a bit uncomfortable with the great post idea of moving your sofa out into the room away from wall. If so, could you accept putting it diagonally from the entrance doorway, across that corner where it is, stopping at the edge of your window? That's a bit of a move outward, still can see the fp and tv, and show off your new rug, which could go diagonally in front of the sofa. Then, if you like that, after a while you could move it on out as Deb K suggests. Sometimes intermediate steps are more doable for us than those big changes.Same with painting; if you could first paint just the fp wall, then later paint other walls...seems some color would really make it more homey. Would you cosider a quite contemporary fixture for the light in the center ceiling? Maybe a bit of red could go there!

As the appearance of the garden has a modernist style with the straight lines and concrete furniture how about a Mondrian influence and add a bold strip of blue? It is a pond and with the right shade it could look really relaxed and contemporary. My daughter's suggestion is a chalky lilac!

All the suggestions above are perfectly good. However, when you have a house that is entirely painted, the options are so endless that it's easy to get stuck. I'd advise either finding photos of comparable homes in colors that you really love, and reproducing a similar palette on your home… or upload a picture of your house to a colorizing site, and play around with various combos. Sherwin Williams has a Color Visualizer that is decent. I don't mind a white house, but feel that the black trim is a bit harsh. On the railing especially- it feels like it is outlining itself too much. Reduce the contrast between the body and the rail and it will enhance the house rather than overwhelm it. You have a lot of choices, so just experiment and go with what resonates with you.

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.
