<b>Use this code to convert HEX colors to RGB that you can use with pdf_setrgbcolor:</b>
<?
$color = "#FF00FF";
$string = str_replace("#","",$color);
$red = hexdec(substr($string,0,2)) / 255;
$green = hexdec(substr($string,2,2)) / 255;
$blue = hexdec(substr($string,4,2)) / 255;
pdf_rect($pdf, 110, 600, 20, 30);
pdf_setrgbcolor_fill($pdf, $red, $green, $blue);
pdf_fill($pdf);
?>
This gives you a pink rectangle!

Here is a snippet of code to create a blue rectangle:
<?php
/*
*pdf_setrgbcolor(pdf_file, float red, float green, float blue);
*red/green/blue are values between 0 and 1.
*It appears that the value is supposed to be a percentage intensity.
*0.0 means a 0% intensity for that color (0 in RGB-scale)
*0.5 means a 50% intensity of that color (127 in RGB-scale)
*1.0 means a 100% intensity of that color (255 in RGB-scale)
*/
//Create blue rectangle
pdf_rect($pdf, 110, 600, 20, 30);
pdf_setrgbcolor_fill($pdf, 0, 0, 1.0);
pdf_fill($pdf);
?>
