Leaving color-deficient-vision issues aside (the usual advice is to not
rely on color alone, but to use other clues such as shape):

Red is used to mean Stop on traffic signs and lights. It stands for
record armed or in progress in the audio realm.

I'd use orange for warnings and red for state or use only one of the 2.

Taking from traffic and audio again, green stands for go!, you-can-pass,
playing (playback, not toys). It shouldn't be used if something is not
in an all-OK state, I think.
