Make the PM Field Turn RED when receiving new PM

[DieselTruck]

Hi, I was wondering how you could make the private messaging area highlight red after you recieve a new PM? Its like that on another forum im on. Any help?

He's the code to make just the Unread 1 turn red if its any help.

<if condition="$bbuserinfo['pmunread']"><if condition="$show['pmstats']"><br /><phrase 1="<font color=red><b>$vbphrase[unread_x_nav_compiled]</b></font>" 2="$vbphrase[total_x_nav_compiled]" 3="$session[sessionurl_q]">$vbphrase[private_messages_nav]</phrase></if><else />

I just need to figure out a code to make the whole little boxed area highlight red.

Thanks in advance
