color/pitch equivalents

When audio frequencies are multiplied up to the light range, into angstrom frequencies (really wavelengths) you get:

herz color pitch
523 yellow c
494 orange b
466   a#
440   a
415 red g#
392   g
370 violet f#
349   f
330   e
311 blue d#
294   d
277 green c#
262 yellow c

It can be noted that the entire portion of the visible spectrum which we mere inferior humans are able to perceive fits neatly into an octave, that the circularity of the color wheel may be not unlike the octave repetitions of sound, and that neither of the things I just said would be considered true if I didn't make the assumption that infra-red and ultra-violet can be regarded as virtually synonymous due to their octave relationship.

But in case this is all in error, I will pass the buck on it by giving credit where credit is due, namely to Helmholtz (Handbuch der physiologischen Optic, 1867, page 237).
