Is it a restaurant? What about a closer picture of the window color? I am thinking something fun and bright like turquoise or cobalt blue- but if it is a restaurant I would choose something in the warmer color family like a golden yellow.

Has the building been powerwashed or cleaned yet? Do you have a sunny day photo?

What about F&B brinjal, or another color that is a rich burgundy or aubergine?

I would go with a richer darker color. It will look really elegant. I would photograph the stone/ brick siding with the color911 app and take it to the paint store. You can adjust the color brightness to be darker with the app and match the color at the paint store. It will be easy and you will have a color that will match your building perfectly. I think it will be the perfect solution.
