Makes sense, but not easy to pluck a specific color out with that technique though. I bought the multicolor pack to tag the different wire harness connectors on our 2005 Hyundai, as apparently all their 3 wire connectors fit each other.
I ain't trying to have to pluck specific color zip ties out the side of a bag when my hands are covered in cruddy engine oil and stuff..
No I didn't need a 100 pack, but that was the cheapest multicolor pack of zip ties I could find, just over $3.
