Error Console does report an interesting little tidbit;

Error: color is undefined Source File: http://mothereffinghsl.com/js/script.js Line: 89

The function in question is

function inputchange(e){

  var target = e.target;
  
  if (target.id == 'alpha'){
    alpha = Math.floor(target.value)/100;
    if (alpha === 1){
      alpha = undefined;
    }
  }
  if (target.id == 'light'){
    var split = color.split('%');
    split[1] = split[1].replace(/\d+/, Math.round(target.value));
    color = split.join('%');

  }
  setText();

Sorry I dont have a full stack trace for you, nor am I inclined to fire up a debugger right now to troubleshoot this any further.
