Random vs noise

{{$t('general.by')}}
Fun
Programming
This program studies what happens when you map noise() or random() to hue. random() covers the whole spectrum and you get all kinds of hues. noise() does not cover the whole spectrum. Reds, oranges and yellows are missing. snoise(), a custom function, tries to improve this by stretching the noise() values. But red is still missing. wnoise() wraps the noise values several times using modulo, and gives a flatter distribution. All hues are present. Sketch from April 2012 ported to JavaScript (I no longer run Java in my browser).
