I've been looking at high end roofing tile websites and one of them has a color expert that made recommendations for house paint colors with their orange/brown roof tiles. Here is a link to some of the schemes they recommend that may give you some inspiration: https://www.davinciroofscapes.com/blog/exterior-color-schemes-autumn/ You can color match to Sherwin Williams brand paint.

Yea it is confusing with the rendering. Sorry about that! The rendering is simply for house design reference. I notated what material is on what part of the house for help in what color should be put where. I’ve read that you’re supposed to use the same color on the same materials. Not sure if that rule is one to follow or not.

Gorgeous house!! Truly!! All I would do is paint the top half/ the greenish color of the house. Leave the bottom which looks like a limestone? Beauty! Would it consider a blue door? Like a deep rich almost navy? I’d paint the brick on the garage to match. Or whitewash. And leave the steps as is. Focus on landscaping? And maybe new garage doors?

A lot depends on where its located for climate, how well its insulated and how well it'll be cooled. Choosing a mid to dark color could be a problem.
