[sdiy] Pink?

Hi all,

I often experience VCOs "too bright", having too much high end in the
sawtooth & pulse waves.
I often experience VCF resonance peaks "too bright", being too strong at
higher cutoffs.
I often experience white noise "too bright", having too much high end...

...while pink noise feels more balanced. Equal power per octave, not per Hz.
Also, good sounding loudspeakers/studios tend to have a bit pink-ish
spectrum roll-off from the sound source to the listener position,
suggesting that some sort of pinkification of clean sounds could be
desirable.

So, why aren't VCOs and VCFs more spectrally pink?
Have there been any attempts historically to alter their characteristics a
bit in synths? :-)
