Explanation
Colors are electromagnetic. Sound is pneumatic. Both are waves, sensed in two different ways, albeit measurable in the same way—with Hertz; the unit of frequency. A single Hertz unit equals 1 cycle per second. A 60 cycle wave sounds like the Flat B hum of a refrigerator, guitar amp, or anything else plugged into the Grid. A 60 cycle wave of light is Invisible.
Now take the 7 Classical Colors (ROYGBIV) and transpose them down 40 Octaves into the audible spectrum of sound. Each Color falls into the region of the 7 Classical Notes (GABCDEF). The rest of the Color Wheel (12 in all) will match up nicely with the 12 Notes. Thus, a simple Transposition of Light, and a Transduction of Light into Sound, will produce the Photosonic Octave as displayed above.
Note: This is purely abstract fun with Man's Sevenfold Systems. Only the Supersynesthete can directly observe these properties in Nature, and integrate Light and Sound in his Sensorium. Fun Facts
The Colors and Notes don't quite line up as nicely as above. G is actually a very dark red, E is more violet than indigo, and F is a deep purple, almost black.
The Primary Colors are red, yellow, and blue. Their analogous notes—G, B, and D—form a G Major triad. Mix the notes together and you get a 'black' chord.
The Primary tones represent the trichromatic blessing of the Day—red rise and fall, yellow orb, blue skies.
The Secondary Colors are orange, green, and violet.
Their analogous notes—A, C, and F—make up an F Major in First Inversion.
Primary and Secondary tones played together form a G Mixolydian Scale. (GABCDEF)
The Secondarys add accents to the Day—orange rays, green flashes, violet twilights.
The left-over 'Tertiary' Colors are red-orange, yellow-orange, green-blue, blue-indigo, and red-violet. Their analogous notes—G#, A#, C#, D#, and F#—form a G#7 Suspended 4th (add 2nd).
The tertiary tones make up an F# Major Pentatonic scale.
Many "Color Organs" have been produced since the 16th
Century which project colored lights onto a screen, or open
curtains to reveal colored glass panes, and other silly arrangements. Russian tone poet Alexander Scriabin invented a clavier à lumières, or "keyboard of light" based on his own stylized synesthesia. But look how dead wrong Scriabin's schema was. It looks nice, but it ain't even close to the real Diatonic Rainbow!
Below is Scriabin's all-time favorite chord known as the Mystic or Promethean Chord. It is a hexachord consisting of six pitch classes: C, F#, Bb, E, A, and D; synthesized from the key of Lydian Dominant. (CDEF#GABb).
