So, this thing is supposed to contain 5 sections

1. Power
   • Red for Normal Charging
   • Green for Fast Charging
2. Data
   • Red for No Data transfer support
   • Yellow for Simple Data
   • Green for High Speed Data
3. Shielding
   • Red for No Shielding (which actually rather results in throwing the cable away, but…)
   • Green for proper shielding
4. Other
   • Red for nothing more
   • Yellow for OTG cables
   • Green for any higher level function like video support and stuff
   • Blue for the combination of Yellow and Green
5. Direction Marker
   • Finally a thin black line to show in which order to read the color marker

I print in 0.2mm layer height which results in 40 layers and change color (in above-mentioned order) on layers 10, 19, 28, and 37

To determine what a cable is capable of, I use a simple USB cable tester tool…
