Colors should be adapted to color blind people. Lines of similar luminosity and close hues are extremely confusing for them.
If it's a personal preference to keep that range of hues then I would recomend changing luminosity, but reducing green/orange/yellow/red line classification to just one of them aggainst blue/white/cyan/grey is much more clear.
