    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.
