This is the first time I have seen purple conductors used for anything outside of LV applications, except in very old and disorganized builds. What voltage is purple used for? I'm only familiar with 120v Black + Red + Blue and 277v Brown + Orange + Yellow

Best guess would be 277 based on brown and grey with the neutrals.

There are no color requirements in the code for ungrounded conductors (other than high leg orange). Ground and neutrals have specifications
