"Just pretend you're wiring airplanes; use white everywhere"
This is common practice even in industrial applications. The difference being wires are tagged on either end to identify them.
I work in an oil refinery where there are set standards and practices as far as wire gauge and color depending on application and voltage. Just sayin'.

OH no...it was entirely sarcastic. I hate that practice. Though I would love to use the religious fanatic-prescribed colour to hang its proponents with after they failed a listening test on the subject.

...what you describe is exactly the "more" I was suspecting. Recall the "discussion" here of a few years ago where the color black was disparaged. Recall too that one of the cited proofs of black's badness was Kimber's purchase of some kind of $100K analyzer that was able to detect electrical differences between various insulation colors. Curiously, at the time, Kimber offered all sorts of cables with black insulated wire. More curiously, I don't see black in Kimber's current offerings.
Too lazy to look up that thread although might be worthwhile to someone else just for entertainment value.
there is ferrous material, along with arsenic and mercury AND cadmium and etc. in this modified element, hence this 'theory'.

Never mind the fact that much "black" coloring is obtained with "nigrosine" dye. Dyestuff chemistry is, very much, "a can of worms".
Carbon black (soot) used in tires would be a POOR choice in wire insulation. Think CF and CC resistors.

Right, Eli... coke comprises 65 to 70 percent of nigrosine dye.
Chemistry is one of the most fascinating fields {to me} that I never delved into.

The dye is what is known as an azo (N=N) compound. In the past, the analine and nitrobenzene starting materials would have been obtained from the byproducts of steel making coke manufacture. I expect that petroleum is currently used, as the starting point.

"Kimber's purchase of some kind of $100K analyzer that was able to detect electrical differences between various insulation colors."
I have no idea what Kimber did. However, I once had the opportunity to test long runs of twisted pair with a Hewlett-Packard cable analyzer that was one of only three in the world. The one I used was recalled from Japan for my company to use. The bottom line is that there is a measurable difference in the characteristics of different insulation colors, or at least the wire they encompass. Note that we were measuring runs of a thousand feet and longer, and the differences were very small. A few feet of wire in an amplifier would show no measurable or audible difference.

Buy Chinese. Bury freedom.
It is plausible that insulation color and some variation of wire characteristic(s) might be correlated but that the color itself is not the actual cause of the variation.
One possibility is that in a wire mfg facility, a particular insulation extruder is dedicated to one or two similar colors to avoid the production inefficiencies assoc with changing colors. Since the dies are manufactured within some manufacturing tolerance, under these conditions, it's probable that any two dies for two extruders (colors) will produce insulation thickness slightly different from each other. This in turn might be expected to result in slight differences in measurable characteristics of say twisted pairs built up of wires from different extruders (colors). It's probably safe to assume that machine to machine production variation is monitored and controlled to the extent that measurable cable differences due to this variation is small and would become most apparent with long runs where differences would be magnified. If this type of dimensional production variation is a cause of variation of measurable cable charactetistics, it seems reasonable to expect correlation of cable characteristic to insulation specific color to be confined to specific production runs of a specific manufacturer. IOW, all else equal, black cable from mfg "A" might be closer to spec than red and white cable from mfg "B" might be closer to spec than their black.
For audio apps, color vs goodness is probably in the mind of the beholder.

...thus my commentary at the end that color goodness is probably in the mind of the audiophile beholder.BTW & FWIW, JOC I got out my handy dandy mechanical Mitutoyo dial caliper and measured the OA thickness of various colors of insulated wire in my stash. There are readily measurable and presumably electrically significant (under proper conditions) differences in OA wire thickness between colors. Same mfg and style. Relatively consistent along the length meas but different amongst colors.

Not to mention thousands of radio, television, mastering facilities, and recording studios are wired with millions of miles of black wire world wide.
Go figure!
Theories such as this are alive as long as some band of religious fanatics say they are. No proof beyond their claim is required. Examine the news, 3-5 million illegal immigrants voted....more of same, with the same sort believing it.

With my apologies to the OP for helping to get off track.

Please don't raise what is, at best, a hypothesis to the level of theory. We speak of Einstein's Theory of General Relativity and its Gravity Law, which have passed, with flying colors, every experimental test devised, to date.
I categorize the insulation color idea as psychotic musings.

I follow color codes but use older coding such as green for filament, yellow for rectifier filament, red for B+, etc.
