It's the system they chose to keep things in check, I'm not aware of their inner works as I'm not their HR guy, even so color coding doesn't suggest a 'class system' (my gmail labels are color coded) it's a just a system to keep things in order.

I am aware of how electronic badges work and that should keep things in check. Worst case they could ask for their id. My point is the electronic system does keep things in order, so why the color? Maybe they should give violet badge to the 15 people working on the search engine. And similar color to different teams that way it is easier to identify.

So that humans can also read the badges without a machine. The same reason they put a picture and your name on the badge, even though the machines don't need them.

Why would they make a badge that only the computer could understand?

Fail-safe? I don't know.
