changing text colors in WML

I have a wml page like so:
______________________________
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="MyCard" title="Journey Planner">
<p align="center">
<b>Please select a query from the following list:</b>
<br/>
<br/>

<a href="Query1.wml">1. When is the next more of transport due?</a>
<br/>
<br/>
<a href="Query2.wml">2. How do I get from one location to another?</a>
</p>
</card>
</wml>

How to I change the color of the links?

How do I but links in to other cards?

Thanks a million
