Roof tiles and color concept for a shed roof house, 15 degrees

Dear Häusle-Bau experts,
Our architect is certainly professionally competent, but when it comes to our design questions, he is not up to date (retiring soon). Especially for me, as a woman, a modern design and a beautiful color scheme are important for our new build. It is a shed roof house with an integrated double garage on a slope (thus three stories, so probably color contrasts make sense).
We envision one or two colors for the facade in the modern grey-beige-brown range; additionally, the roof tiles should not be too wavy (flat roof tiles?) in a matching color.
If someone sends us a proposal that we then use, I would like to send the idea giver a gift (book voucher or a specialty from the Black Forest). Many thanks, your Tina

Hello building expert,
I would have done it if it weren't so boring... As mentioned, it is a three-story shed roof house (square, practical, good) without any additional . The roof over the terrace and the basement, that is, the double garage, is built into the hillside. We have to deliver design/color decisions on Monday and had hoped to find valuable ideas here. Too bad...
Still, greetings from the beautiful Black Forest,
Tina

PS. Insight: building under time pressure... is not good!

Good morning

You have some strange requests about how we should help you.
Do you really expect colorful painted squares from us?
Your house surely has windows and doors, specific dimensions, roof overhangs .....
With the request for colored cubes, surely no one here can give valuable tips for building design.
