title: How $_filter->getHtml() is generated?
body: <p>I need to edit the result of <code>$_filter-&gt;getHtml()</code> function.</p>
  
  <p>The <code>$_filter-&gt;getHtml()</code> returns an HTML content with <code>ul</code> and <code>li</code> combination for product attributes and I want to apply some modifications to this block.</p>
  
  <p>What I want exactly is to convert some color names (e.g. red) to theirs hex equivalent (<code>FF0A0A</code>).</p>
  
  <p>Do you have any idea on how to change the block contents?</p>
