What marker do you use to mark them? Is the ink durable and easy to read?

I bought a cheap pack of 5 colors of 3m electrical tape. Each cable gets one or two pieces of tape:

Data:

White if usb2

Blue if it supports USB 3 data (because 5Gbps USB 3 ports are mostly blue)

Green if TB/USB4/40Gbps

Power:

None if low/no Power Delivery

Yellow for 45W PD

Red for 65W+ PD

A label maker, as they said they use, prints durable and easy to read labels.
