Colour of Light that is Resonant with the Pitch Above

Details
The resonant colour of light that is 41 octaves above an F4 at standard pitch A4=440 has a frequency of 767.96 THz. This colour has a wavelength of 390.37 nm. The equivalent RGB colours (shown above) that approximate this colour of light are #57009e. The frequency of an F4 at standard pitch A4=440 is 349.23 Hz. At a temperature of 22.22°C, the speed of sound is 345.31 m/sec. Under these conditions, an F4 at standard pitch A4=440 has a wavelength of 98.88 cm.

Documentation

This calculator lets you specify a note and observe the colour that is consonant with that note. “Consonant" means that the colour has a frequency that is some number of octaves above the frequency of the sound.
