Is there a way for a certain property string field to be formatted with color, bold, etc?

Summary:

Good day guys.

I have this warning message from a return validation call and I put it on the Edit Form as a string property (e,g, cm_warning_message). Would there be an easy way to make the text in color like red for emphasis purposes to the field reps? I am trying to do a trial and error using the XSLT formating from the property setup but I feel I am doing it incorrectly.

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template><span style="color:red;">activity.cm_warning_message</span></xsl:template>
