neural irregularities as pink noise, which is also called 1/f noise
A few minutes of fooling around with a color tool will show you that the spectrum of pink is flat (white) with a notch at the green and the 1/f spectrum is brown, nothing at all resembling pink. The misnomer of pink to label 1/f seems to come from a misconception that flat + a pole at red is pink (it’s not—it’s red) and 1/f (it’s not—it’s flat with a pole at red).
It is a pity this idea has gotten so much traction into the English language as it is so horribly wrong. It’s like one of those things that Pauli would describe as “not even wrong.”
