If you're experiencing issues with the LED color of a specific key on your PCMK 2 HE keyboard, we're here to help.

Here are some steps you can take to troubleshoot the problem:

1. Update the firmware of your PCMK 2 HE keyboard to the latest version by visiting bbb.pulsar.gg, 

navigating to Settings, and selecting Update. 

2. To apply the latest version of the web driver, press CTRL+F5 in your browser to clear the cache. 

3. Use the RGB color test mode (FN+T) to check if the LED colors are working correctly. 

Cycle through the different colors (RED, GREEN, BLUE, SKY BLUE, PINK, YELLOW GREEN, WHITE, Bibimbap setting mode) to see if any specific color is not displaying correctly.
