Hi there @Doug Copeland,
I'm no expert in HTML, but based on the details provided, it looks like your code is attempting to assign a color to the text itself.
Perhaps the code you're looking for is something that highlights/colors the space around the actual text.
If this is correct, maybe you can give this html code a whirl:
<div
class="appsText"
align="center"
style="padding:0px 0px 0px 0px;
border-style: solid;
font-size:18px;color:#008000;">
<b>
<span style="background-color: #008000">
<%=Projects Master Data.Project Health%>
</span>
</b>
</br>
I hope this helps or gives you some ideas.
Good luck!
