As said, the numbers passed to imagecolorallocate() have to be 0..255.
To split a given hex string into its color parts, you could use string
functions or something like this:
function imageColorAllocateHex($im, $color) {
$c = hexdec($color);
return imageColorAllocate($im,
0xFF & $c >> 0x10,
0xFF & $c >> 0x8,
0xFF & $c
);
}
Usage:
$color = imageColorAllocateHex($im, '00FF00');
