Why does the colored output for cargo mentioned at 11:15 not work for me both in Linux Ubuntu and Windows terminals (for which I also enabled colored output in said terminals)? Am I missing something? running cargo with '--color always' also doesn't do anything for me

[JohnPywtorak]

fwiw there is no color output for cargo help, does not work, yet. I think it is comming

[CyborusYT]

this update had my 2-year-old pr in it!
