 Randomising Text Colour
Mmm? I can't post in "PHP Scripts" so I'll dump it here. 
Here's a cute little thing that I found in my travels that randomises the colour of texts etc - - - -
Da Script:
<?php
function get_random_color()
{
for ($i = 0; $i<6; $i++)
{
$c .= dechex(rand(0,15));
}
return "#$c";
}
?> <?php
echo '<span style="color:'.get_random_color().'; font-weight: bold;">'.$r['username'].'</span><br />';
?>
And one gets something like this:

Re: Randomising Text Colour
Thanks for sharing Mort, there are similar (not identical!) scripts in bbcode.php that you can use here.

Re: Randomising Text Colour
Yep, I knew that was there Luca , but IMHO they're both toys for those who don't know any better.
Both have foreground-background colour compatibility problems with words and letters disappearing, and that's what I mean by toys!
Imagine if one was to script them to use the forum css tags?
No maybe not!

Re: Randomising Text Colour
I am currently successfully using the following code to randomly change the color of specified text ("quotations" - see below) each time the page is reloaded. The only problem is that the colors are too random. Instead of the code I now have, I'm looking for code that would allow me to define a distinct list of colors through which the text would randomly rotate each time the page loads. In other words, I want to choose each of the randomly loaded colors of my text. Hope that makes sense... Perhaps some kind of an array?

Re: Randomising Text Colour
Hi, sorry for the delay.
Can you tell me which colors you'd like?
