EMG vs Neural noise

Is it accurate to say that EMG noise is white while neural noise is pink? In Mike’s ICA video, the EMG noise here appears white above ~15hz https://www.youtube.com/watch?v=AKCK7DXa0gY&t=797s

I wouldn’t say that EMG is white. A “white” noise spectrum is flat – uniform across all frequencies. EMG definitely has some clear rhythmicity around 15-30 Hz. There is also white noise added on top of that, though.
