Best way to generate a random color in javascript? [closed]

Answer 1

Here's a way to generate a random color and provide the minimum brightness:

function randomColor(brightness){
  function randomChannel(brightness){
    var r = 255-brightness;
    var n = 0|((Math.random() * r) + brightness);
    var s = n.toString(16);
    return (s.length==1) ? '0'+s : s;
  }
  return '#' + randomChannel(brightness) + randomChannel(brightness) + randomChannel(brightness);
}

Call randomColor with a value from 0-255, indicitating how bright the color should be. This is helpful for generating pastels, for example randomColor(220)
