Random Color generator for PHP (original) (raw)

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')); // "#15056d"

RandomColor::one(array('format'=>'hsv')); // array('h'=>249,'s'=>95,'v'=>43)

RandomColor::one(array('format'=>'rgb')); // array('r'=>21.0,'g'=>5.0,'b'=>109.0)

RandomColor::one(array('format'=>'hslCss')); // "hsl(249,90.48%,22.575%)"

RandomColor::one(array('format'=>'rgbCss')); // "rgb(21,5,109)"

RandomColor::one(array('format'=>'hexa')); // "#15056d71"
