Change username color with a profile field

[Bioman2k]

Hi,

I've made a World of Warcraft board for my guild.
Yesterday, I added new custom profile fields like player's name, player's class, player's server...

I would like to know if it's possible to attribute specific color to members when then correctly choose their class.

For example, if I register to my board and choose "mage", automatically, my name in every forums will be colored in #558A84.

To do that, I added the following CSS into additionnal.css file :

/* WoW Color Class
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*/
.chaman {
	color:#0070DE;
	font-weight:bold;
}

.hunter {
	color:#ABD473;
	font-weight:bold;
}

.warlock {
	color:#9482C9;
	font-weight:bold;
}

.hunter {
	color:#ABD473;
	font-weight:bold;
}

.dk {
	color:#C41F3B;
	font-weight:bold;
}

.druid {
	color:#ff7d0a;
	font-weight:bold;
}

.warrior {
	color:#c79c69;
	font-weight:bold;
}

.mage {
	color:#69CCF0;
	font-weight:bold;
}

.monk {
	color:#558A84;
	font-weight:bold;
}

.paladin {
	color:#f58cba;
	font-weight:bold;
}

.priest {
	color:#000000;
	font-weight:bold;
}

.rogue {
	color:#fff468;
	font-weight:bold;
}

Any idea to do that ?
Thank you all in advance.
