I am probably too late, but I would think about a soft olive green, rather than a sage. I think the warmer tones of the olive would be nice in the shady space, and with a red door and warm white trim, along with the roof color, would be a wonderful combo! Have you considered adding simple trellises on either side of the lone window on the left? I would be nice with the cottage feel of the home, and would give some visual weight to balance the three windows on the other side. Paint the ceiling of the porch in a light blue, and change out the railings to wood ones. A charming cottage! Your current home is wonderful, and I can understand you hating to leave. But down the line, especially since remodeling is your passion, you will have something even more amazing, I am sure. For now, the cottage may feel small, but will also give you a sense of coziness and security that could be an island of peace in the storm.

Grey green would look beautiful with a bright white, perhaps? I would also recommend some landscaping and outdoor lighting to help!

Look like you live in a hot climate. I wouldn't remove the awnings. They don't detract. The yellow door will certainly add a "wow" factor. I wouldn't feel like I had to do it though, unless the house isn't selling . . . depends on your market. Easier IMHO to just prune and clean up the landscaping so it doesn't hide the porch and windows, which are nice features. Maybe a little bistro set on the porch once you trim or even downsize what you have there. It looks a tad busy. If you love the plants you can pot them up and save for your move but really I would simplify because that's what a lot of buyers want. Maybe three all the same low flowering shrubs. Don't know your zone. Something like those small mounded spireas . . . You're clearly a gardener but your prospective home buyers may not be.

I like the La Paloma gray better as it has some brown in it, making it a warmer tone that I think works better with your brick.
