I am not asking the question "how do you describe the color purple." I am asking what specific combinations of red-green-blue are in this shade of purple. This is defined quantitatively for colors of every hue. I may prefer baby blue to burnt orange, that's my personal preference. But I should be able to specifically define each color that is repeatable. Finding verbal descriptors for whether red is raspy or warm is not the point. For example, to say a guitar has balanced tone says nothing to me. To say striking this note creates multiple peaks in these frequencies and suppresses these others seems like a more precise way to describe subtle differences in sound quality.
I'm sure we have some physicists and sound engineers who can solve this and present a repeatable, if somewhat simplified model analogous to the RGB scale for color. It has probably already been done.
Yes, it has as I noted in my post above: specifically the section referring to harmonic content as related to sound character and waveform risetime/decay as related to attack. Another example: playing without nails will produce a warmer sound with less "attack", i.e., fewer higher order harmonics and a slower risetime in the waveform...as in less percussive sound. To measure this, simply record a note and then use a computerized programme to analyze the spectral content...or use a spectrum analyzer app:

Ya that's what I'm tawkin about.
