What grey noise is
White noise is equal in energy at every frequency, but our ears hear mids and highs as louder, so it sounds bright. Grey noise is shaped to cancel that out. The lows and the very top are lifted until every part of the range sounds about the same loudness.
The result sits between pink and brown noise: balanced, a little deeper, with less hiss than white. It's a good pick if pink feels thin and brown feels muddy.

Frequently asked questions
Is grey noise the same as gray noise?
Yes. Grey and gray are the same thing, just different spellings.
Grey noise vs. pink noise: which is better for sleep?
Pink is softer on top; grey has fuller lows and sounds more even. Try both at a low volume and keep the one you stop noticing.
