Sounds Beauteous I: Postmortem

Equalization is always contextual; pink noise should not be imitated to a T. That being said, 'pink music' within corresponding, conventional paradigms are the best renditions of said (intended) music.

Grey noise is a slightly superior ambition insofar as higher frequencies are concerned; grey noise is recommended to be replicated above 10K Hz (principally above Ear Canal Resonance) whilst frequencies below are to remain pink.

To summarize, a pink-grey exegesis is an exemplary demarcation of equal apparent loudness.
