Forums / Cotonti / Support / Grup color Core hack how can do ?

change your function:

function cot_build_user($id, $user, $extra_attrs = '')
{
	global $db;
	if (!$id)
	{
		return empty($user) ? '' : $user;
	}
	else
	{
		$gdata = $db->query("SELECT gru_groupid FROM cot_groups_users WHERE gru_userid = $id LIMIT 1");
		$row = $gdata->fetch();
		return empty($user) ? '?' : $link='<a href="'.cot_url('users', 'm=details&id='.$id.'&u='.$user).'" class="group'.$row["gru_groupid"].'">'.$user.'</a>';
	}
}

open your css file and add anywhere:

a.group5{
	color:#FF0000;
	font-weight:bold;
}
a.group4{
	color:#000;
	font-weight:bold;
}
a.group3{
	color:#CC0;
	font-weight:bold;
}
a.group2{
	color:#ddd;
	font-weight:bold;
}
a.group1{
	color:#ccc;
	font-weight:bold;
}
