TL;DR http://vasile.github.io/swiss-transit-colors/
This repo contains the vehicle route colors used by public transport operators in Switzerland. It's useful for public transport apps which deal with vehicle lines and their associated colors.
The config file covers only a bit of all swiss public transport operators for which I used manual color pickers to get the right colors. Contributions are welcome!
Examples from Swiss Transit App stations lookup
