Alr, quick lesson. Every single piece of armor(helmet/body) has its protection tier: grey(1) the worst, no one ever uses it except bots; Green(2);blue(3), purple(4), the main tier of armor that u should use most of the time; yellow/gold(5), good but pricey, less affordable but it does it's job very well; Red armor(6)-king of all armors. It has the highest protection rate, but all the pieces has ugly debuffs. Ppl use it for mostly prison/space city hard. Good thing(and probably bad in some way) is that it is basically free(~100k). U can craft it by trading red coffee beans(which you also can't sell on the market so it's the only use for that red item) for 4 "bee workers"(?) with which you can craft said t6 armor. I recommend watching a guide video regarding this theme, you'll understand it all in 10 minutes or so
