More food for thought: the discovery of the above track, found
here, flowed from the curious recollection of a famous book,
Gödel, Escher, and Bach. It strays from the OP considerably but zeros in somewhat on some immense challenges that find a purchase here — primarily relating to perception. Here, there's also tempo and pitch causing havoc with the head and, as such, it's an interesting litmus test. I don't see colors shifting but I do get more and more riled as the thing winds up

I guess, I see red, in that sense
Douglas Hofstadter’s Pulitzer-winning book had a huge impact on the study of various intelligences, when he published it — perhaps even more interesting now, as we move into an age where many of those historical challenges are being felt out, and sometimes without the
human comprehension we then imagined we might require for the adequate resolution of problems of intelligence.
Troy's track's interesting, maybe, for testing the ear's perception relative to color perception, imagining, the mind's eye, the psyche, etc., moving through the octaves. But, for me, it generates moods, more than colors

Synesthetes may get a bang out of it.
A couple of other explorations:
Is there any chromatic analogue of the Shepard tone? seems to be hitting the mark. Some other experiments, like the so called Blue Diamonds Optical Illusion, reflect similar imaginings. And
Generating Shepard and Risset tones looks with a more mathematical eye into some of the detail.
I won't be fielding any questions here, on these tangents. All this is way beyond my pay-grade. Not that I don't find it interesting, it's just that my ignorance is truly profound and I wouldn't be any help whatsoever. I've not spent enough time on the subject. It is fascinating though, all these loop de loops, the chicanery of color perception, and random blendings of awarenesses. I wonder what quantum physics might bring to the table. I think maybe we
bipedal creatures have been dulled somehow to the more subtle depths of perception, some of us at least. I'd love to have a
bird's eye view of all this
