Harmonic Color, Harmonic Purity, Harmonic Vividness and Visual Color

I guess we should try and define some of these terms and then [I should] try even harder to stick to using them correctly.

*Harmonic Purity is analogous, in my mind to a tuning fork. A ‘ringing’ purity with all subharmonics intact and appropriately long decays. The opposite to harmonic purity is ‘blanched’ [i.e. washed out. Anyone else use a different term?]

*Color is how much subharmonics are present at all frequencies and SPLs and dynamics, especially in the smaller, more subtle notes. The opposite to having lots of color is Leanness.

*Harmonic Vividness is the cross product (multiplication) of Harmonic Purity and Color – when they are both present the music harmonics are very brightly colored – very real [or better than real since many live performances have lots of soft people around you absorbing various harmonics]. Harmonic Vividness is the real goal here with respect to harmonics.

*Harmonic Resolution is how many different harmonic tones are audible within a single major note. The lack of harmonic resolution [no term for this yet] is for example a middle ‘C’ note where all you can hear is the one frequency, growing loud then soft. With lots of harmonic resolution that same note has audible delineatable harmonics in the related octaves, as well as some harmonics at freq a little above and below [if this is a real world instrument] and all of which decay at different rates – and sometimes reinforcing and/or diminishing each other- lending a fullness and richness and character to the note.

From a recent deranged comment (of mine :-)):

“McIntosh can be said to have color, but it is low on harmonic purity and ‘vividness’. I do not see this as a particularity good thing. There is this Visual Color I see when I hear equipment. Valhalla is bluish silver. Jorma Prime is orangish brown [more like a burnished orange, actually]. McIntosh… is uneven, kind of like a faded-in-some-areas worn plaid pastel shirt. The Ongaku is…”

[as I continue to think about the mental colors I associate with things that I like the sound of…]

… like sunlight on a bar of gold [a lot of bright colors on a background that is slightly gold]. The AN DAC 5 Signature was as close to a pure rainbow (or prism, think Dark Side of the Moon album cover) as I have heard.

Sometimes colors are hard to pin down (for me, anyway). The Nordost Odin power cord is white. The Odin interconnect is slightly grayer than the Odin PC. The AN PALLAS is a smallish rainbow [actually, 100s of smallish prisms. and the Lamm ML3 is millions of smallish prisms]. The Lamm ML2.1 is purplish grayish white.

I do not see a mental color when I think of speakers, or rather I see the actual color of the speaker itself in my mind, which is *so* boring 🙂

Anyone else have colors they associate with equipment?
