RandomColor A color generator for PHP

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'));
  // "#f4c804"

RandomColor::one(array('format'=>'hsv'));
  // array('h'=>49,'s'=>98,'v'=>96)

RandomColor::one(array('format'=>'hsl'));
  // array('h'=>49,'s'=>96.0799999999999982946974341757595539093017578125,'l'=>48.96000000000000085265128291212022304534912109375)

  // "hsl(49,96.08%,48.96%)"
