String to pastelcolor script. If added to your project you can simply use: "string to be converted".getPastel(); to convert the string to a pastel color.

stringToPastel.js

String.prototype.getPastel = function (rgb) {
  var radix = (!rgb) ? 16 : 10;

  var hashCode = this.split("").reduce(function (a, b) {
    a = ((a << 5) - a) + b.charCodeAt(0);
    b = ((b << 5) - b) + a;
    return a << b;
  }, 0);

  var rad = function (bitshift) {
    return Math.round(
      ((((hashCode >> bitshift) & 0xFF) + 255) / 2)
    ).toString(radix);
  };

  return (radix === 10) ? "rgb(" + rad(24) + "," + rad(16) + "," + rad(8) + ")" : "#" + rad(24) + rad(16) + rad(8);
};

usage:

"swag".getPastel(); => "#809b88"

"swag".getPastel(1); => "rgb(128,155,136}"
