Hi Thea. Your new home looks amazing already (even without paint) - congratulations! You have plenty of visual interest with the stonewalls, balconies and stepped architectural features, so I would suggest you keep your colour scheme fairly low key and neutral so as to not compete (less is more, sometimes!). You could pick out the lightest coloured stone and work with that; if it's a grey tone, for example, choose a similarly toned paint colour.

go with grey and white combination by highlighting the borders

In my opinion a great combination for your exterior walls, especially if you're interested in sustainability, would be a mix of light gray with a subtle touch of blue. This blend creates a modern and calming look while considering solar options. You could go for a light gray base and then add blue accents or trims. Additionally, you can install solar rooftop system into your house design to enhance energy efficiency and add an eco-friendly touch to your home.
