"""
Link voicemeeter status to two blink(1) devices
- blink device #1 will show output mute status
- blink device #2 will show microphone mute status

# Note that the colors used by the device compared to what is shown in the blink control
# utility program are 2 shades brighter.  So if you want to use the rich pink color of
# B40486, you have to actually choose 2 colors darker (2 down in the grid), 610B4B.
