The System I use has no rhyme or reason. its simply something I adopted early on and it has stuck over the years.
This goes back to my old Analog days, writing on the desk with colored markers, it was just easier to identify.
I have begun to change some of my colors due to automation, selecting brighter colors on VOX tracks so I can see the waveform clearer through selections. One thing has not changed though. and that is color groups. if you notice below- my colors are grouped depending on the instrument groups velocity's. For example: Guitars are all in the Red group but acoustics are lighter, Lead Guitars are darker.
-DRUMS/PERCUSSION: blue
- BASS: yellow
- STRINGS: Light brown/gold
- PIANO: gold
- OTHER KEYS: dark brown/gold
-ACOUSTIC: light red
- RHYTHM GUITARS: red
- LEAD GUITARS: dark red
- VOCALS: green
I have also adapted a naming system to categorize tracks. (there's also a link for the template if you'd like)

it doesn't just save headaches, it speeds up the process.
