php - generating 12 random color for each month -

i have setting setup pallet color fusionchart bar graph

"palettecolors": "#594a2d,#660057,#6e8cff,#3d0c4e,#9ce6ae,#009e78,#001f8f,#ff7852,#ebff26,#0073e6,#f05eff,#00decc", 

im trying generate 12 random color code each month of year put in setting...

or use 12 colors code above make random each loop ?

 #594a2d,#660057,#6e8cff,#3d0c4e,#9ce6ae,#009e78,#001f8f,#ff7852,#ebff26,#0073e6,#f05eff,#00decc 

what tried far..this working random color..but if want use predefined color ?

<?php $rand = dechex(rand(0x000000, 0xffffff));?>  "palettecolors": "<?php echo('#' . $rand);  ($d=0;$d<12;$d++) { echo(',#' . $rand); }   ?>", 

there shuffle function move elements of array random positions. can shuffle array predefined colors , use first twelve elements of it:

$colors = explode(',', '#594a2d,#660057,#6e8cff,#3d0c4e,#9ce6ae,#009e78,#001f8f,#ff7852,#ebff26,#0073e6,#f05eff,#00decc');  shuffle($colors); ($i = 0; $i < 12; $i++) {     echo($colors[$i]); }
