Personalized Map Colours Revision

I need help with changing the color of driving routes on a map I designed. This task requires precision and an eye for detail. A usual proficiency with design software is crucial, but specific experience with customizing maps will make this process much smoother. I need this project completed at the earliest convenience. The stars are the starting points. We need any overlap of the routes as one color and if the route is just coming from one star but doesnt cross over with the other star's route it will need to be another color. In total there will be 3 colors for both maps.

Ideal skills:
- Map customization
- Graphic design
- Proficient with design software
- Exceptional attention to detail
- Quick turnaround time
