Mapping of color to sound

Music is governed by harmony, whereas visual art can be appreciated with a much looser application of visual stimuli.

On the chromatic scale, doubling the frequency of a pitch increments by one octave. For example, note A4 is 440 Hz, so A5 is 880 Hz.

Since sound requires such precision to be appreciated as music, we can apply this doubling rule to color to achieve a harmonic conversion. The spreadsheet below shows this mapping.

Color-sound mapping

I still have a lot of work to do. For example, color frequencies increase well beyond the range of the basic colors. I'm hoping this can equate to light or dark versions.

I dream whit this man, and now i find your article. I will study this project

Somewhere I read that people with synesthesia see the pitch on a different octave the same, say like C = green, in all the places in keyboard. C2 is the same as C4 and so.

So why don't you divide the visible spectrum by 12, and assign the same colors with different brightness on the octave. Like A0 black and C8 white... I'm working also on this, I share a text I found on the web:
