Accidentally writing Serial.begin(115200) twice in the setup function caused the red signal to disappear but Blue and Green remained. Printing to serial monitor still worked but red component was missing. Obviously not an issue that needs fixing as you shouldn't have two Serial begins, but something to be aware of.
