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.

IMO white would be very appropriate for the house but you need to remove the stone IMO first . Not one house maylee posts is anything like yours and honestly IMO yours needs to be one color . I also think you need huge plant pots filled to overflowing with plants that flower and all placed on that huge patio surface Black windows and doors would be awesome but not cheap. IMO a contrasing trim will cheapen the house and its style I love long ranch style houses and IMO look best when all elements are kept simple

Update- we have begun to paint, and we decided to keep the garage door the same color as the body of the house. The downspouts will also be the same color. We chose BM White Dove. Here is a picture of what it looks like on the main part of the house during the day and during the evening. I’ll upload more when they finish. Thank you for your help!

So you've categorized this as Spanish/Mediterranean/Southwest style which are actually three pretty different styles. Based on the existing detailing, this is really a pueblo-style bungalow (i.e., Southwest). I say that based on the flat roof and horizontal trim detail over the windows. To bring some charm and dimension to the facade, I'd suggest a board-and-batten style vertical siding if you really do have to stick with vertical. (If you are referring to historic district or like requirements, however, I'm quite certain you could get permission to go back to the original surface if you can establish the vertical siding isn't original. Consider investigating that first, since stucco would make the most sense.) That is not really historically correct, but no form of verticla siding really would be, and since the original integrity of the house is long gone, I'd be more focused on charm. I think a creamy white is the right color for the siding, though a pale green might work too. I would consider painting the stucco an adobe color like the below. To me, it's not the siding but the windows and doors that really are killing the aesthetic of this house - the material and the lack of ornamentation/moldings. Consider replacement with higher-quality wood windows with period-appropriate wooden sills and moldings. If you have to keep them until they fail, I'd add some wood or Azek window boxes under them, particularly the shorter one to the left, more as a distraction than anything. I'd get rid of the window over the door with the house number, which looks like it belongs in a storefront, not a house. Restoring charm to a house usually requires using historically-apropriate materials that are expensive, like real wood, and adding decorative detailing like exposed beams and stone. Below are some examples of beautiful adobe-style houses that have this type of detailing. You cannot recreate it with metal plate-glass windows. Your little house is cute and I love the courtyard!
