That would be the role of stylesheets and CSS classes.

 .primary-fill {
   fill: #ff66cc;
 #ship, #shields, #exhaust {
   visibility: visible;

Given something like:

 <g id="ship" visibility="hidden">
   <path d="whatever" class="primary-fill"/>
 <g id="shields" visibility="hidden">
 <g id="exhaust" visibility="hidden">

(not sure about the "frame" bit)

[ n.b. Stylesheets will take precedence over presentation
attributes, but not CSS properties specified with style="" ]
