   If you want to display all number in a specific color: change all colors code in gdimg.php (your simplecaptcha plugin folder)

   replace all this
   

   $switch = rand(1, 4);
   if($switch==1) { // Blue color
   	$r = rand(000, 000);
   	$g = rand(000, 000);
   	$b = rand(000, 000);
   }
   if($switch==2) { // Blue color
   	$r = rand(000, 000);
   	$g = rand(000, 000);
   	$b = rand(000, 000);
   }
   if($switch==3) { // Green color
   	$r = rand(000, 000);
   	$g = rand(000, 000);
   	$b = rand(000, 000);
   }
   if($switch==4) { // Yellow color
   	$r = rand(000, 000);
   	$g = rand(000, 000);
   	$b = rand(000, 000);
   }

   with this and it will show only black numbers
   

   $switch = rand(1, 1);
   
   if($switch==1) { // Black color is 000,000 find color coder at internet
   	$r = rand(000, 000);
   	$g = rand(000, 000);
   	$b = rand(000, 000);
   }

   Removing numbers distortion or wave:
   just find this
   # Testing adding sinwave to image
   below that line of text you will find something like:
   

   $offset = rand(1, 10);
   $graph = true;
   for($i = 1; $i <= 96; $i++) {

   Solution: OFFSET should be put on (0, 0).

   How to change number quantity (edit gdimg.php)
   by default it will only show 6 numbers from 0 to 9.
   

   //we generate random number for use<br />
   $str = rand(0, 9) . rand(0, 9) . rand(0, 9) . rand(0, 9) . rand(0, 9);

   Edit it to show only 4 or less numbers from 0 to 9.
   

   //we generate random number for use
   $str = rand(0, 9) . rand(0, 9) . rand(0, 9) . rand(0, 9);

   Just remove rand(0, 9) to remove a number.
