Random color generation using PHP

Question

I\'m trying to generate random HTML colors in PHP, but I\'m having trouble getting them to look similar, or in the same family. Is there some function I can use to generate

Answer 1

Another short and simple version: change the mt_rand(X, Y) values in order to generate desired colour range: (0, 255) - full range; (180, 255) - pastel palette; (0, 100) - dark palette; etc...

function gen_color(){
    mt_srand((double)microtime()*1000000); 
    $color_code = '';
    while(strlen($color_code)<6){
        $color_code .= sprintf("%02X", mt_rand(0, 255));
    }
    return $color_code;
}
