This is a Processing sketch that returns colors and sounds corresponding to the astrological signs of the zodiac, in a fairly direct (and probably underwhelming) way. I have some ideas for developing more creative interactions, but for here and now I am documenting the correspondences and some simple code to interact with them.
I had some options while mapping Case’s colors which were based on the RYB (subtractive) color model, to the RGB (additive) color space. I chose Green (008000) instead for Lime (00FF00) for green, and the middle of Red (FF0000) mixed with Blue (0000FF) for violet (= 800080, i.e. Purple), instead of Magenta (FF00FF). I could have used Aqua (00FFFF) for green-blue, or mixed Blue (0000FF) with the darker Green (008000) (= 004080), but instead chose the middle of Blue (0000FF) mixed with Lime (00FF00) to make my green-blue (008080). To make orange (FF4000), I used the middle of Red (FF0000) and Yellow (FFFF00).
If you have any ideas about the color correspondences in RGB/CYM space, please leave a comment below.
The sounds are generated by a monotone sine wave. I got the frequencies for the musical notes from this page.
