What is the best method to name twisted pair wires with same colors in datatable csv

I have a 12pr cable where individual wire colors are duplicated but the pair combination is unique. I am using $$index$$ spool_name color and cond_id in the following way:

1 WHT_BLU WHT_BLU 1

2 BLU_WHT BLU_WHT 2

This is the first pair and index 1 is the white wire and index 2 is the blue wire. I attached the complete file.

Is this the best method for naming the individual wires in the datatable .csv datatable file? Is there are standard naming convention for this?

What is the best method when each pair has a black wire? (ie BLK_RED, BLK_BLU, BLK_WHT...)

Note: These wires are not striped.

Thanks!
