Traditional Color Scheme for Roof & Soffit

I'm looking for a professional to help me select and apply colors for my home's roof, soffit, and fascia. The style I'm aiming for is a traditional and classic one, with a preference for neutral tones like grey and beige for the roof. The soffit and fascia should be in contrasting but complementary colors to the roof. We have settled on going with DaVinci Brownstone Slate roofing material.

Ideal skills for this project would be:
- Expertise in color theory and design
- Experience with home exterior color schemes
- Understanding of traditional and classic aesthetics.

Please provide samples of your previous work in this style, along with your proposal.
