    Hi all,

    My rPi zero with WS2812b setup is giving me an issue. I can get the LEDs to light up and send colors to them in Hypercon, however, when I select red it lights up green, and when i select green it lights up red. I have tried configs with all the different RGB byte orders and even when I make it something like GRB the color issue persists.

    Thank you for any help.

    This is probably because you switched the colors twice, once in Hyperion and once in your Arduino code (given that you are using an Arduino to drive these LEDs).

    The solution is to set RGB at one place and GRB at the other place.
