1. Pass the "Three-Second Rule"
- Who you are (Logo/Name)
- What you do (Plumbing, Heating, Electric)
- How to reach you (Website or Phone)
2. Design for the "Indy Grey"
- White on bright blue: A classic, high-visibility choice for HVAC.
- Safety yellow or orange: These colors cut through fog and rain effectively.
- Reflective accents: Consider using reflective vinyl for key elements like your phone number. This ensures your brand remains visible.
