%player_colored_ping% has colors in reverse order

[hensih]

I updated to the latest version and my ping starts at red and goes green if it gets laggy.

Should be the other way around.

Nothing in the code suggests this behaviour.

On a high ping will the expansion return &c or &4 and on low ping will it be &a.

Double-check that the config of PAPI does have the right values

  player:
    ping_color:
      medium: '&e'
      high: '&a'
      low: '&c'

You are correct.
