There are a few mistakes, or I misspoke a few times in this video. But for the most part, it displays how you can imagine the "devils tone" as a mirror on the fret board, and play a melody using Major and minor 3rds, then play the mirror image, or palindrome of that melody. They sound very complimentary.
Here is the visualization of how these Major and Minor 3rds can be viewed as mirror images of them selves. The colored lines connected the relative mirror images.
Here is a nifty page that displays the frequency and wavelengths of each note in A4=400Hz. You can actually change the A4 and see how the various notes change.

Also, here is an image of the color spectrum found on the web.
In addition, I know my math is a little off saying that the tri-tone or "devils tone" is the half of the wave length. But here is a really nice video with an indepth explanation of how you have to use irrational numbers for tuning a piano.
Furthermore, here is a nice site that goes into Rodin number maps.

Please comment, share, ect.
Moreover, see if you can create some melody palindromes and expand upon this idea.
Thanks so much for watching,
Take care and Gob bless.
