Sound and light...

share the fundamental nature of vibration. The sounds we can hear have a much lower frequency than light that is visible to us, however, there is a range of sound frequencies that have corresponding consonant colours.

Colour of Music focuses on this specific range of sound frequencies that have corresponding consonant colours. The colour bars are created using pitch to colour calculators, plotting chord progression and picking out root notes, then applying the Colour of Music palette to your chosen piece of music.

Colour of Music explores a specific relationship between sound and colour: a direct relationship between the continuous spectrum of frequencies of electromagnetic energy in the band of visible light and the pitches of sound in a continuous frequency spectrum of sound that are 40 octaves (a factor of 240 = 1,099,511,627,776) below the frequencies of visible light.

The resonant colour of light that is 40 octaves above an F#4 at standard pitch A4=440 has a frequency of 406.81 THz. This colour has a wavelength of 736.93 nm. The equivalent RGB colours that approximate this colour of light are #750000, based on a modified version of Dan Bruton’s colour approximation algorithm. I have developed my own colour palette based on this algorithm.

Sound is based on vibrations of air molecules as a moving compression wave, and light (and hence colour) is based on an electromagnetic wave. While “frequency” is a measure commonly used for both compression and electromagnetic waves, the two types of waves are quite different, therefore, Colour of Music is not an exact science, it is a creative mission to expose hidden language.
