you could change it like this:

</vb:if>

<form class="vbform block" action="sendmessage.php?do=contactus" method="post">
<h2 class="blockhead">{vb:rawphrase send_email_to_forum_administrator}</h2>
<div class="blockbody formcontrols">
<h3 class="blocksubhead">{vb:rawphrase your_details}</h3>
<div class="section">
<div class="blockrow">
<label for="name">{vb:rawphrase your_name}:</label>
<input type="text" class="primary textbox" id="name" name="name" value="{vb:raw name}" tabindex="1" style="background-color: #333 !important" />
</div>

<div class="blockrow">
<label for="email">{vb:rawphrase email_address}:</label>
<input type="text" class="primary textbox" id="email" name="email" value="{vb:raw email}" tabindex="1" style="background-color: #333 !important" />
</div>
</div>

#333 being the hex-representation of your preferred color. #333 is a dark grey, #000 is black, etc.
