Show HN: Synesthesia, make noise music with a colorpicker

tevans3 Thursday, January 22, 2026

This is a (silly, little) app which lets you make noise music using a color picker as an instrument. When you click on a specific point in the color picker, a bit of JavaScript maps the binary representation of the clicked-on color's hex-code to a "chord" in the 24 tone-equal-temperament scale. That chord is then played back using a throttled audio generation method which was implemented via Tone.js.

NOTE! Turn the volume way down before using the site. It is noise music. :)
