Funny that you mention pink noise. After reading the headline alone, I wondered if pink noise had been considered. I find sometimes brown noise works well, and sometimes pink noise works well, depending on mood. White noise is almost always too harsh for me. I also use an app called Chroma Doze from F-Droid, which can generate different spectrum noise. My only gripe with it is there's no "presets", or no way to export/import presents.
