There is no way in hell I would even consider painting walls in a house I had never lived in.....and even without my furniture in place. The sun in the morning and the sun in the evening....what reflects off a garage a fence or a neighbor's house how your beloved hutch looks all affect the colors and tones of the paint and finishes I would consider. Colors look very different at night then they do on a sunny day and walls look different in an empty room than in the same room with furniture. Tell your friend to move in before he begins to select paints and finishes. I know it's a pain to move out of a room to refinish it....but I believe he will be happier in the long run. I have seen too many people who had to choose the colors and finishings in a new house, repainting in 3 months because the color was too dark or looked like white in the day time or because with the tile the walls look wrong and it's easier to paint than re-tile. It's fun to plan new finishes....but don't do more than fix a leaky faucet until you have been in the house for a while. Our first house was brand new plaster on lathe and we were told not to paint for at least 6 months to allow the plaster to fully cure. By the time the 6 months was over, I was so sick of all the white walls, I painted the living/dining area something like harvest wheat.....which was like dark mustard when all the walls were that color! I could hardly wait until the paint was dry to re do it!...But I was over reacting to 6 months without color!

FYI, a gable is just the wall under the pointy part of the roof. The decorative boards on your garage gable are, I think, battens, which are just pieces of wood that cover up the seams between the wood siding. They are primarily decorative, and if you don't like them, you could probably take them off. (On older Tudor homes, you might see a similar effect created with actual beams, and those would be structural and not just cosmetic). Because your house has the whole California/Mediterranean thing going on, I don't think that highlighting the battens is going to be in keeping with the style of the home, so I would favor painting them to blend in. You could remove them, but you might find that makes the garage gable too plain and boring. As others have suggested, you will have to choose a paint that works with the stone, unless you want to remove the stone. The stone definitely has some of that peachy thing going on, although it has some more muted grays that you could work with. Based on your pics and my images for Waynesboro Taupe (that is, take this with a grain of salt since computers don't always render color right), I don't really like the Waynesboro Taupe with the stone. Here are some colors I liked better: Chelsea Gray Gettysburg Gray Sandy Hook Gray Fairview Taupe Iced Marble (this one runs to blue-gray, which might be too much out on a limb for your neighborhood) I think that you could keep black as an accent color (I like black and taupe together) for the shutters and maybe the front door. I would like to see the garage door go dark, either matching the wall color or even going a few shades darker. The white draws too much attention to what really isn't a great feature of the house (I'm not a fan of prominent garage doors in general, let's not make them stand out more than they have to.) Benjamin Moore's color viewer has a sample picture called "Ageless Tudor" that has some characteristics in common with your home (stone, board and batten gable) that you might want to use for experimenting. Or I think you can upload your own photo, although I can't vouch for how well that works.

Congratulations! I think something a bit darker might unify the exterior, maybe something to match the lighter brick. Then use your door & shutters or drapes (can't tell what I'm looking at in the windows) to add interest or accent or contrast.

It is a charming house! With the exception of the later-added retaining wall (@ right of drive) the yard looks like it has enormous possibilities. I would consider dark taupe as an option for the shutters. I don't care for the fad of colored doors as a way to add excitement to the house's looks. White, same as trim is a good look, IMO. But the door must be high quality door, including the storm door. The house definitely needs more expansive steps, landing and walks.
