The Color of Sound - Pitch-to-Color Calculator
Here is something fun to play with. Sound and colour have long been debated as having links and here is a website that makes the link explicit. It looks complicated but all you have to do is play with the note input on the left hand side and you will see the colour change at the bottom.
The link is made here by the wavelengths of sound and the wavelengths if light being directly compared. For people like me who do not understand the science much, the website was reasonable easy to understand and I had fun playing with the colours too!Â http://www.flutopedia.com/sound_color.htm
