Edit: Yeah I wrote "WoW Color Hack" twice in the title and I don't know why...you can thank marijuana for that.

I've decided to release this...

Here's an excerpt from the read-me:



Code:
WoWColorHack.flt

-=Preamble=-
I'm quite surprised that no one has released
anything similar yet - the theory behind
this dates back to the alpha days. Hell,
I first used this filter on my own alpha
sandbox.

-=Theory=-
*Almost* all text in WoW either allows for
or at one time allowed for the use of color
codes. These color codes look like this:
The following text is |cFF00FF00 GREEN
The tag is |c and the hex-code is obviously
the color. These codes are used throughout
the game and are how most, if not all,
colored text is handled.

So why not just
/say |cFF00FF00 Marijuana
and be done with it? Well, Blizzard made the
client automatically replace any |'s that
typed with ||'s (which ||c is NOT a tag).
Then the client just displays
|cFF00FF00 Marijuana
(replacing ||'s with |'s for display
purposes only).

Thus, you have to circumvent the client's
alterations. A packet filter in WPE Pro
would work nicely. Perhaps if I make my
own color tag and replace it (using a
filter) with the actual color tag, I will
bypass the client.

Thanks to Diablo II's ridiculous color
code shenanigans, Blizzard was smart this
time and made their server start checking
for color codes sent by you. Therefore
filtering |c into your chat message will
do very little because the server will
change the |'s to ||'s. Lucky for you,
they haven't done that everywhere.
It's up to you to try it out here and
there.

!!!!!!!!
ON OFFICIAL BLIZZARD SERVERS:
I know it still works in your guild
information text, your guild note
text, and your guild MOTD.

I know it used to work in mail but
last time I tried, it returned a 'Mail
Database Error' or something to that
effect.
!!!!!!!!
ON EMULATED SERVERS:
As far as I have tested, it works in all
text.
!!!!!!!!

Pretty much everyone who has developed
a server for WoW (presumably} knows about
these codes and how they work which is
why I'm surprised this sort of filter
has yet to be released to the public.

-=Hack=-
This filter replaces all occurances of
'fc' with '|c' sent from the client.
Simply typing
fcFF00FF00 Marijuana
will send
|cFF00FF00 Marijuana
to the server.
Just open it in WPE Pro, turn on the
filter, and start your colorful
adventure.

-=Detectability=-
I cannot guarentee how detectable this is.
It requires WPE Pro which injects code
into WoW - which Warden is known to be
capable of watching for. On the other
hand, I've yet to ever be banned from it
(and have been using it on and off since
day one). Still, my situation may be a
little different than most which prevents
my ban.

Also, it would be hella-easy for Blizzard
to to just add a few extra lines of code
to their servers that automatically ban
anyone who sends text with a |c in it
instead of a ||c. Would they? Doubt it.
Could they? Def.

Obviously virus free since it's just a WPE Pro filter.

Here's a download:

On a final note, nothing this does is "client side only". In the above screeenshots, the colored text is visible to everyone.

Oh yeah, and please read the damn Read Me. This hack expects that you
know how to work WPE Pro (not in an advanced way - just open this
filter).
