Creamy white or a very light tannish color, like sand , , maybe with a very light touch of green . I’m not a fan of gray exteriors on houses such as yours.

I think I’d like bright clean.

Like the others said above, creamy white is a better color for this house. Here is a pretty one in Benjamin Moore Mayonnaise

I checked mayonnaise and it is actually a light tan. I would like to stay away from yellow/ brown tones.

Why not a nice grayed. sagey green like the sagebrush and some cacti like the agave in your awesome landscaping.
