What is it?

This is a port of the randomColor.js script created by David Merfield.

RandomColor generates attractive colors by default. More specifically, RandomColor produces bright colors with a reasonably high saturation. This makes randomColor particularly useful for data visualizations and generative art.

Examples

Once you have included RandomColor.class.php on your app, calling RandomColor::one($options) or RandomColor::many($count, $options) will return a random attractive color. Beneath is the live output of 36 generations.

RandomColor::many(36);

You can also pass an options object to randomColor. This allows you to specify the hue, luminosity and the format of colors to generate.

Format

RandomColor::one(array('format'=>'hex'));
  // "#039619"

RandomColor::one(array('format'=>'hsv'));
  // array('h'=>129,'s'=>98,'v'=>59)

RandomColor::one(array('format'=>'hsl'));
  // array('h'=>129,'s'=>96.08,'l'=>30.09)

RandomColor::one(array('format'=>'rgb'));
  // array('r'=>3.0,'g'=>150.0,'b'=>25.0)

RandomColor::one(array('format'=>'hslCss'));
  // "hsl(129,96.08%,30.09%)"

RandomColor::one(array('format'=>'rgbCss'));
  // "rgb(3,150,25)"
