Well, due to IE's poor support of CSS, you'll have to explicity define colors for each section. Example:
#section1, #section1 a:link {
color: #112233;
}
#section2, #section2 a:link {
color: #445566;
}
<div id="section1">
Here is a <a href="http://google.com">link</a>...
</div>
<div id="section2">
<a href="http://yahoo.com">This</a> is another link, though it matches the color of the rest of this section.
</div>
