TOPIC: Take out Random color of Captcha letters?

I want to take out the random color of the Captcha letter
Iknow it have to do with:

$color = ImageColorAllocate($im, rand(0,0), rand(0,0), rand(0,0));
$rk_color = ImageColorAllocate($im, 128, 128, 128);

and

ImageTTFText($im, $size, $angle, $x + 2, $y + 2, $rk_color, $font, $textstr);
ImageTTFText($im, $size, $angle, $x, $y, $color, $font, $textstr);

in the captcha.php

But what to do to have the text image only one color....

Hm, as you can see in the demo:
compojoom.com/index.php/demo.html
the letters are always black, the background is different. You want to change the background or what?

I already change the background image to better reflect the look and feel of the site.
If you go at:

It seem that sometimes only the pale gray shadow appear but not the top black text.
Sometime it happen when you go to the page or if you click the code box enough time.
I really need to fix that....

Did you fix your problem? For me the captcha seems fine.

If you click the captcha enough time you will see it become pale gray at one point.

don't use rand(0,0)
just replace it with 0 to become black color.

Work perfectly!
Thank You!
