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'));
  // "#71a510"

RandomColor::one(array('format'=>'hsv'));
  // array('h'=>81,'s'=>90,'v'=>65)

RandomColor::one(array('format'=>'hsl'));
  // array('h'=>81,'s'=>81.8200000000000073896444519050419330596923828125,'l'=>35.75000000000000710542735760100185871124267578125)

RandomColor::one(array('format'=>'rgb'));
  // array('r'=>113.0,'g'=>165.0,'b'=>16.0)

RandomColor::one(array('format'=>'hslCss'));
  // "hsl(81,81.82%,35.75%)"

RandomColor::one(array('format'=>'rgbCss'));
  // "rgb(113,165,16)"
