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'));
  // "#3a8203"

RandomColor::one(array('format'=>'hsv'));
  // array('h'=>94,'s'=>97,'v'=>51)

RandomColor::one(array('format'=>'hsl'));
  // array('h'=>94,'s'=>94.1700000000000017053025658242404460906982421875,'l'=>26.2650000000000005684341886080801486968994140625)

RandomColor::one(array('format'=>'rgb'));
  // array('r'=>58.0,'g'=>130.0,'b'=>3.0)

RandomColor::one(array('format'=>'hslCss'));
  // "hsl(94,94.17%,26.265%)"

RandomColor::one(array('format'=>'rgbCss'));
  // "rgb(58,130,3)"
